Your genetic family tree is not the same as your genealogical pedigree–and not just because of non-paternity events and adoption. Here’s how.
Your genealogical pedigree, if you are diligent or lucky (or both!) can contain hundreds, even thousands of names and can go back countless generations. You can include as many collateral lines as you want. You can add several sources to your findings, and these days you can even add media, including pictures and copies of the actual documents. Every time someone gets married or welcomes a new baby, you can add that to your chart. In short, there is no end to the amount of information that can make up your pedigree chart.
Not so for your genetic pedigree.
Your genetic pedigree contains only those ancestors for whom you have received some of their DNA. You do not have DNA from all of your ancestors.
You do not have DNA from all of your ancestors.
Using some fancy math we can calculate that the average generation in which you start to see that you have inherited zero blocks of DNA from an ancestor is about seven. But of course, most of us aren’t trying to figure out how much of our DNA we received from great great great grandma Sarah. Most of us just have a list of DNA matches and we are trying to figure out if we are all related to 3X great grandma Sarah. So how does that work?
Well, the first thing we need to recognize is that living descendants of Sarah’s would generally be our fourth cousins. Again, bring in the fancy math and we can learn that living, documented fourth cousins who have this autosomal DNA test completed will only share DNA with each other 50% of the time.
Yes, only half.
Only half of the time your DNA will tell you what your paper trail might have already figured out: that you and cousin Jim are fourth cousins, related through sweet 3X great grandma Sarah.
But here’s where the numbers are in our favor. You have, on average, 940 fourth cousins. So if you are only sharing DNA with 470 of them, that’s not quite so bad, is it? And it only takes one or two of them to be tested and show up on your match list. Their presence there, and their documentation back to sweet Sarah, helps to verify the genealogy you have completed. It also allows you to gather others who might share this connection so you can learn even more about Sarah and her family. Plus, if you find Jim, then Jim will have 470 4th cousins as well, some of which will not be on your list, giving you access to even more of the 940.
This genetic family tree not matching up exactly with your traditional family tree also manifests itself in your ethnicity results, though there are other reasons for discrepancies there as well. Read this article to learn more about why ethnicity results may not match.
In short, this DNA stuff is not a stand alone tool, but if you combine it with your traditional resources, it can be a very powerful tool for verifying and extending your family history. Remember, just because a cousin doesn’t show a match in DNA, it doesn’t mean there isn’t a genealogical connection! Genealogical research and primary sources can still prove connections even if DNA doesn’t show it.

Have you thought about starting a blog to share your family history research, but just haven’t done it yet?
- It’s a free, no fuss-way to publish your family history as you write it, one little piece at a time.
- It shares your family stories with loved ones who are interested enough to read your short snippets.
- It’s “out there” on the internet for long-lost relatives to find and connect with you.
Well, Lisa has just republished a FREE 5-part podcast series on how to start a genealogy blog! It’s from her original Family History Podcast, a step-by-step how-to series for genealogists. I’ve just finishing remastering the last of the how-to-blog episodes, and I’ll tell you, they are inspiring!
In fact, after one of the episodes originally aired, listener Will Haskell contacted Lisa and said he thought he’d start a blog. I was curious–did he ever do it? He DID! I found Will’s Genealogy Blog here and started reading. He’s posted all kinds of great information about his family history. He hasn’t posted much recently, so I contacted him. What he said was really interesting:
“Lisa definitely was the instigator in starting the blog. I have not been keeping up with the blog in the past couple years. Being a business owner has cut in to the family history research and blogging quite a bit. I am still amazed at how many people visit my blog even without regular updates. I have been able to reconnect with several relatives through the blog.”
So that’s another great aspect of blogging: it’s not a forever commitment, and it often continues to reward you even when you’re not actively blogging! Check out the blog series here:

Historical photos and images can bring depth and understanding to genealogical findings. In the case of sharing your family history with others in your family who don’t share your passion for genealogy, they are an essential part of bringing family history to life.
One of the best free online resources for historical photos is the Creative Commons at Flickr.
Flickr is a popular photo, image and video hosting and sharing service. It’s a great platform for sharing your favorite photos with family and friends. It’s also an excellent place to find images that fit into your family history.
An important part of the Flickr world is Creative Commons, which describes itself as part of a “worldwide movement for sharing historical and out-of-copyright images.”
Groups and individuals alike upload old images, tag and source them, and make them available to others through the Creative Commons. And when it comes to groups, the list of participants is impressive.
The British Library photostream features over a million images in its photostream! And a robust collection of historical photos and images can be found at the (U.S.) Library of Congress photostream, with over 34,000+ photos.
Searching the Creative Commons
When searching the Creative Commons, be sure to look for your favorite libraries and historical societies. If you don’t find them today, don’t worry. Check back regularly because new content is being added all the time.
Here’s another example of what you can find at the Creative Commons. The Netherlands Institute of Military History (Nederlands Instituut voor Militaire Historie) has a photostream.
“Exercise Field Artillery Corps” album, image AKL092038, Netherlands Institute of Military History uploads at Flickr Creative Commons, https://www.flickr.com/photos/nimhimages/16026248719/.
According to the Netherlands Institute of Military History blog, “The Institute exists to serve all those with an interest in the military past of the Netherlands. Its sphere of activities covers the Dutch armed forces on land, at sea and in the air, from the sixteenth century until now. The staff of the NIMH administer a unique military history collection containing approximately 2 million images, of which they will be uploading many to the site.”
Back in 2015 when we first wrote about their brand new photostream it only included a couple dozen images, like the one shown here. Today they have well over 3,300.
Tips for Finding and Using Historical Photos at the Creative Commons
Searching for Historical Photos: On a photostream home page, click the search icon (magnifying glass) just above the first row of photos in the upper right corner. A search box will pop up at the top of the page. Enter Keywords to search for images within that photostream. (Image below)
Location isn’t Everything: Just like with brick and mortar libraries, don’t let the location of the library or archive hosting the photostream fool you! Their collections are not limited to only items in their area. If you’re in search of something specific, try the Flickr Advanced Search page here.
Understanding Downloading and Copyright: Those who post images to Flickr Creative Commons offer different rights to those who want to download and use their images. Described here (and searchable here by the kinds of rights you want), those rights may include the ability to use a photo as long as it’s for noncommercial purposes and proper credit is given. Perfect for a responsible, source-citing genealogist!
10 Favorite Flickr Photostreams with Historical Focus
It would be impossible to list all of the potential photostreams at Flickr’s Creative Commons that feature historical photos, so I won’t even try. However, I’m happy to provide this list of favorites, which illustrates the breath and depth of possibilities. I hope it inspires you to search out your favorite library or archive at the Creative Commons.
(Organized by number of photos)
Internet Archive Book Images
5,240,000+ Photos
Though not currently organized by Albums or Galleries, there is something here for absolutely everybody! Use the search feature to zero in on what you want. (See tips section below)
The British Library
1,000,000+ Photos
A gloriously eclectic mix of images. Just one example: World War I: The Canadian Experience. This photo album covers 1895 and 1924, and contain depictions of Canadians’ experiences of the First World War. From the British Library: “Either produced by photographers on home soil or individuals in Europe employed by Lord Beaverbrook’s ‘Canadian War Records Office’ the photographs provide a wide ranging account of the many Canadians involved in and impacted by the war.”
The National Archives UK
20,000+ Photos
the UK government’s official archive contains more than 1,000 years of history, so their photostream is not to be missed! Nicely organized into Albums focused on location, the images offer a sampling of their massive holdings.
The U.S. National Archives
16,500+ Photos
Nicely organized into a vast array of albums, these photos represent only a small sampling of the photographs in their collection which totals more than 25 million photos and 20,000 graphic images. Early on they focused on uploading photos from the Women’s Bureau, the Environmental Protection Agency, and a few staff favorites. According to the National Archives, “These photographs, most taken by agents of Federal agencies over the years, cover a wide range of subjects and themes documented in the work of the United States government. Higher resolution versions of many of these images can be obtained from the U.S. National Archives by following the links located below each image.”
