What is DNA Painter

Lisa: What is DNA painter?

Blaine: DNA Painter is a really incredible website for genealogists working with their DNA results.

There are several different aspects of the website, including chromosome mapping, which is assigning segments of DNA to particular ancestors. There are some tools for testing hypotheses, like What Are the Odds. And there’s also the Shared Centimorgan Project, which allows you to hypothesize what a genealogical relationship to a match might be based on the amount of DNA you share with that match.

About Blaine Bettinger and the Shared cM Tool

Lisa: As I understand it, that’s kind of how you got involved with DNA painter, or how DNA painter evolved. Tell us a little bit about your background and your work with the Shared cM Tool.

Blaine: I have been a genetic genealogist, essentially, for almost 20 years now. I started in 2003 with my first DNA test and I’ve been a genealogist since middle school. So, I’ve been working in this DNA field for a long time.

Once autosomal DNA testing came along, we discovered that there wasn’t a lot of information about known ranges for various relationships. For example, if I test myself in a first cousin, how much DNA would we share? What might be considered a normal amount? What might be an abnormal amount, and so on? So, I started in 2015 collecting data from test takers, for example, sets of first cousins. We wanted to be able to answer questions like what’s your relationship? And how much DNA do you share? Once I started to collect enough of that data, I could get an idea about what the range for various relationships might be.

Johnny Pearl, the incredible creator behind DNA painter, asked if he could host a version of the Shared Centimorgan Project at the website. I was thrilled to see that. And so now there is a hosted version of the Shared Centimorgan Project with all of those ranges for about 40 different relationships at a DNA Painter.

Shared cM tool at DNA Painter

Lisa: Well, that’s really kind of the whole industry, isn’t it? It’s very collaborative. And it’s amazing how it seems like different people have different pieces of the puzzle.

How to Get Started with DNA Painter

Is DNA Painter free? How does someone get involved? Do we need an account?

Blaine: It depends on what you want to do. If you want to use the Shared Centimorgan Project tool, there’s no cost for that. That’s free for anyone to use. So, you would just go to DNA Painter, and either register for a free account, or have no account and still be able to use the Shared Centimorgan Tool.

If you want to start chromosome mapping at DNA Painter, you do get one free map. That’s the assignment of those segments to ancestors. But if you wanted to have maybe a couple maps, you would have to run into having a subscription to the site, which is well worth the money it takes to have a subscription because it’s so valuable in helping you organize your matches and working with your segment information, and so on.

What the Shared Centimorgan Tool can tell you about your DNA

Lisa: You mentioned the chromosome mapping, and the Shared Centimorgan Tool, and What Are the Odds? Can you give us an example of a burning question that a genealogist might have, and that the answer is, “you need to go to DNA painter to do that”?

Blaine: So, let’s say for example, you get a new match at testing company ABC, and that match shares 400 Centimorgans with you. The immediate question is, how is this person related to me? That’s a lot of DNA to share with someone but without a frame of reference you don’t really know. Is it could that my eighth cousin? Is it my sibling? What are the possible relationships?

If you go to DNA Painter and the Shared Centimorgan Project, you pop in 400 Centimorgans. What that’s going to do is it’s going to give you the possible relationships that that could be. And so that’s going to significantly narrow down your search for your genealogical relationship to this new DNA match that you have.

Lisa: Oh, yeah, that would be huge.

DNA Painter for Beginners

So, does this require much technical know-how? Do people have to feel like they’re scientific in nature, or can anybody do this? Could a person new to using genetic genealogy feel like they could do this?

Blaine: Absolutely! And I think one of the great things about DNA Painter and Johnny is that everything is designed to be user-friendly. The website is incredibly easy to understand and interact with the Shared Centimorgan Project. I’m of course biased, but I think it is also created in such a way to be easily understandable. The results of that search for 400 centimorgan relationships is going to give you an output that I think is easy to interpret and understand.

DNA Painter Best Tip

Lisa: What’s your favorite tip? What do you recommend that people either not miss, or make sure that they do while they are at DNA Painter?

Blaine: Bookmarking the Shared Centimorgan Project I think is really important. I think many genealogists use it on a daily basis. Again, I’m biased, but the value of the tool is that it’s free. And it’s so important to helping you understand the possible relationships for your DNA matches.

Now, years from now, once you do this enough, you can start to remember some of the ranges. You can kind of do it in your head. But until you get to that stage, bookmark that site, and you can just refer to it quickly when you’re working with your DNA results.

Lisa: That’s a good idea. It’s very easy to just drag that URL right on to your web browser bookmark bar and have a bookmark ready to go.

Genetic Genealogy Book by Blaine Bettinger

You’ve really been on the forefront of all of this genetic genealogy. And I know that you’re the author of a book, tell us the name of your book.

Blaine: The name of my book is the Family Tree Guide to DNA Testing and Genetic Genealogy, second edition.

The Future of Genetic Genealogy

Lisa: What do you think we can look forward to in the future of genetic genealogy?

Blaine: I think it’s really hard to predict in some ways. Some of the tools we have now are our tools we couldn’t even have imagined several years ago. And what’s fueling this growth is the growth of the databases themselves.

For example, just in the past week or so Ancestry came out with a new tool called Side View that allows the grouping of your matches into the two different sides of your family: your paternal side and your maternal side. We couldn’t have imagined a tool like that just a couple of years ago, but it’s because of the size of the database.

For me, the future is two-fold. Number one, it’s the development of these new tools by the testing companies. And it’s also development of new tools by third parties, including the tools like the Shared Centimorgan Project, DNA Painter, and so on. I think we’re going to see more and more tools come out that allow us to work with our results in new and interesting ways.

Lisa: Do you think they’ll ever be a time where the tools and the machine learning that eventually there’s enough data accumulated between people who have tested and people who do genealogy and people who do both, that it could actually automate this process?

Blaine: I do think there’s a huge potential for automation. The one thing that I think is missing right now is that most genetic genealogists, most genealogists period, function as islands. And there isn’t enough collaboration in a way that allows us to benefit from each other’s work. And so, I think there needs to be a way to start to tie together in a more collaborative way, the work that we’ve done. For example, assigning segments of DNA to ancestors.

If I figure out that this stretch of DNA came from Jane and John Doe, that’s great, but that lives on my computer. If there were a way to share that with the world in an easy and collaborative way by clicking a couple of buttons, then, once we have thousands of people doing that, we could have a pretty incredible database and start to really work in a collaborative fashion.

Lisa: Collaboration certainly has been the key behind so much of what’s grown in genealogy.

Was This My Ancestor’s Neighborhood? Using Google Earth for Genealogy

by Lisa Cooke | Jul 15, 2015 | 01 What's New, Google Earth, images, Inspiration, Maps, Photographs, United States

by Sunny Jane Morton

When Lisa blogged recently about Google Earth’s 10th birthday, it reminded me of something on my family history “to do” list. A few years ago I found a postcard of what I thought was an ancestor’s neighborhood. Could Google Earth confirm it?

Jones Street, Olyphant, PA, 1910. Image courtesy of Michael Grayson.

Lisa uses Google Earth’s powerful 3D renderings of the world’s streets to identify where old pictures were taken. I knew from deeds, a plat map, and addresses on censuses and draft registrations that the O’Hotnicky lived on a certain block of Jones St. (now named Grant St.), around the corner from and behind Holy Ghost church.

This postcard of “Jones Street, Olyphant” looks like its viewpoint is from the end of the block behind the church. This would mean the tall tree shown here was shading–and blocking our view of–the O’Hotnicky home.

I opened Google Earth and flew to “117 Grant St, Olyphant, PA.” The initial view, hovering from above, was promising. The camera icon shows where I thought the photo was taken. The left arrow points to the former line of trees, in front of the ancestral address. The right arrow points to the church tower behind.

Unfortunately, when I enter Street View at that exact spot, the new church on the corner and a tall apartment building block the view that would have been seen a century ago. There is no Street View available on Grant Street itself so I couldn’t move up the street toward the church. So I moved into Street View along the side street (parallel to the bottom of the photo).

In the opening between two buildings, Google Earth gave me a glimpse of the church tower. I compared the postcard view with Google Earth’s photo. The church towers look so similar: a simple cross on top, pointed copper roof, arched tower and the building roof line. Even more striking to me is the white frame house. Was this the same white house shown in the postcard view?

These two visuals taken together–the church tower profile and the position of the white house–seem consistent with my theory of where the photo was taken. Which means that yes, indeed, this 1910 postcard shows the trees in front of an ancestor’s home as they appeared 105 years ago.

Google Earth can fly you to an ancestor’s neighborhood–and whatever clues its current landscape gives you into the landscape of the past. Click here to watch Lisa’s free video about using Google Earth for genealogy!

NEW!! Access the 1939 Register Online at Findmypast

by Diahan Southard | Nov 2, 2015 | 01 What's New, British, Census, Findmypast, Records & databases

The 1939 Register–the most comprehensive population survey EVER of England and Wales known–is finally searchable online!

Today FindMyPast, in association with the U.K.’s National Archive, has launched a digitized, searchable version of the 1939 Register. This major record set fills a major gap at a pivotal time in history.

“Anyone can now discover their family, their home and their community on the eve of WWII,” states a FindMyPast release. “Until now, the most recent information available was the 1911 census. Owing to the 100 year rule, the 1921 census will not be released until 2022, while the 1931 census was destroyed in the war and the 1941 census was never taken. The 1939 Register therefore bridges an important 30-year gap in history.”

“In September 1939, WWII had just broken out,” explains Findmypast. “65,000 enumerators were employed to visit every house in England and Wales to take stock of the civil population. The information that they recorded was used to issue Identity Cards, plan mass evacuations, establish rationing and co-ordinate other war-time provisions….

“Each record includes the names of inhabitants at each address, their date of birth, marital status and occupation….Comprising 1.2 million pages in 7,000 volumes and documenting the lives of 41 million people, the 1939 Register opens a window to a world on the brink of cataclysmic change.” Some of the records even include changes made clear up to 1991.
Additionally, Findmypast has added unique period photographs, infographics, regional newspaper articles and maps “personally tailored to each record.” They are promoting a “rich and unique user experience unrivaled by any other family history research tool to date.”

What about privacy concerns? This is a relatively recent record set: more recent than national censuses that DO have privacy restrictions on them. About 28 million records have been cleared of privacy restrictions. The remainder will remain temporary closed, “either because the individual recorded is still living and less than 100 years old or proof of death has not been verified….The Register will be updated weekly….Records will also be opened as people reach the age of 100 years+1 day.”

Interestingly, it appears individuals may have the ability to show proof of death to have records released: “Findmypast, working with The National Archives, will have an ongoing process to identify records which can be opened on proof of death provided either by matching against robust data sets or supplied by users.”

The Register is free to search on Findmypast. Charges apply to view the records, with discounts for subscribers and pay-per-view packages starting at £6.95.

Research WWII Ancestors in Action, At Home, Under Fire

by Lisa Cooke | Sep 7, 2016 | 01 What's New, Book Club, British, Military, United States | 2 comments

Research WWII ancestors with these three tips. The experiences of our ancestors during World War II add a rich texture to their personal history. Whether in the military, on the home-front, or those living in neighborhoods that became battle zones, find their stories with these helpful tips.

In Everyone Brave is Forgiven by Chris Cleave, our current Genealogy Gems Book Club title, we read about different ways Londoners experienced World War II. A soldier shipped out to Malta, a female War Office recruit, a child evacuee, a civilian running regularly for underground shelters as bombs fell; these are just a few of the book’s poignant stories.

That diversity of experience was part of our ancestors’ lives, too. Some served in the military and some kept the home fires burning. Some even dodged bombs or bullets in their own neighborhoods! Many experienced the horrors of concentration, POW, or other types of interment camps.

As many different experiences as they had, there are just as many ways to research their lives during WWII. Here are several scattered examples of the kinds of records and resources you may find. Do a little of your own exploring to see whether the kinds of materials below exist for your WWII ancestors.

Research WWII Ancestors: The Soldier

Two get-started guides for U.S. researchers:
- Finding Your Father’s War Revised Edition: A Practical Guide to Researching and Understanding Service in the World War II US Army by Jonathan Gawne.
- A free PDF guide from The National Archives (US): “Finding Information on Personal Participation in World War II.”
Military service records and databases such as those for the Australian Army, Australian Royal Navy and Australian Royal Air Force; Britain’s Royal Air Force; Russian Red Army forces and more.
Military yearbooks for specific units.
Records of women’s service in units such as the U.S. Cadet Nursing Corps.
Prisoner of war records for combined military forces, United States, and British and Commonwealth forces.
Military burials such as the Commonwealth War Graves Commission online database of British, Irish, and Commonwealth WWII casualties.

Research WWII Ancestors: On the Home Front and in Harm’s Way

Lisa’s grandmother heading off to work at Kaiser’s Richmond Shipyards, c. 1941

Millions of civilians’ lives were directly affected by the war. Many women entered jobs for the first time in their lives or began doing new types of volunteer work. Families faced rationing, price controls, and blackouts. Some unfortunates found themselves in the path of the war.

This article from the U.S. National Archives has an excellent review of the kinds of online and offline resources you can read to learn more about U.S. home front activities. Reading Everyone Brave is Forgiven will introduce you (in a re-imagined way) to the experience of Londoners caught in The Blitz. You can also explore The Blitz in this interactive map of the bombings.

Speaking of maps, one resource your home-front family would have used to follow troop movements and the progress of the war were the Stanley Turner maps. His collection contained a unique series of action-packed maps. These can add a fascinating and colorful layer of understanding to your family’s experience during this time.
