Do you need help solving your family migration patterns? A groundbreaking new scientific study uses DNA and family trees to map migration routes across North America.
Family Migration Patterns Revealed in Genomes
A new study published in Nature Communications represents a ground-breaking development in using DNA for genealogy. The article from the AncestryDNA Scientific Team is titled Clustering of 770,000 genomes reveals post-colonial population structure of North America. Or, in more understandable terms, “Your DNA can tell us where you came from in America in the last 500 years.”
Wow, right? So, how did they do this?
The power really is in the numbers. In this particular paper, they started with using their autosomal DNA test on 770,000 people. Some of them were AncestryDNA customers who had consented to be part of the research. From these 770,000, they learned quite a bit about the migration patterns of early Americans. As Ancestry analyzes more individuals using these same principles of correlating genetics and genealogy, this data will improve and be able to tell us even more about our heritage. Even though it takes a large data set to figure out the relationship between our DNA and migration patterns, it really comes down to the relationship of two people.
To start, Ancestry determines how just two people are genetically related. Then, they find how those two are related to a third person, again, looking only at pairs of people. This goes on and on until everyone in the group as been compared. They use a graph to plot those relationships, with those more closely related clustering around each other. And then it happens. The point where we see the marriage of genetics and genealogy suddenly appear by adding in the family history information for each of these individuals in the cluster.
What they found was astounding. They have displayed the data in Figure 3 shown below. It is a map of the United States with colored dots scattered across the landscape. The location of the dots corresponds to the genealogy of those tested, while the color of the dots relates to their genetic clustering. Those who cluster closest together are the same color. The result is a nearly perfect rainbow, with buy anti anxiety medication online uk each color holding its respective spot on the map, with very little overlap between groups.

We might be tempted when looking at the map to think, oh, well, of course there is a large population of European Jews in New York, everyone knows that. But this isn’t their family history, their accent, or their culture telling us this – it is their genetics!
As if that wasn’t exciting enough, the scientists describe how we can trace family migration patterns of different groups over just a few generations. They specifically mention French Canadians and Cajuns/Acadians, but the same principle can theoretically be applied to dozens of other groups.
Family Migration Patterns and Applying these Findings
So what does this mean for you as a genealogist?
It means we are getting closer than ever to being able to tell who you are and where you came from using your DNA.
For example, let’s say you have an ancestor in Texas about 4 generations ago, but you aren’t sure where she came from. Your DNA could tell you that you fit into the Lower South group, meaning that your ancestor likely hails from the south. Or, maybe your genetics identify with the Upland South, which means you need to explore records from Arkansas, Tennessee, and North Carolina.
This is just a glimpse into the advances that genetics are bringing to your genealogy toolbox these days. So it’s high time to go “all in” to learn about genetic genealogy! We recommend The Family Tree Guide to DNA Testing and Genetic Genealogyby Blaine Bettinger. You’ll love this book if:
You’ve got brick walls that traditional research methods haven’t been able to break down
You want to take advantage of the hottest tool in genealogy
You’ve already taken a DNA test and want to know what comes next

THE ARCHIVE LADY: Library Archives Canada Co-Lab
The Library and Archives of Canada (LAC) has introduced a brand-new crowdsourcing opportunity for genealogists or anyone interested in records transcription: Co-Lab.
The LAC has put a call out for volunteers to be part of a collaborative project to transcribe, add keywords and image tags, translate content from an image or document and add descriptions to digitized images using “Co-Lab” and the new “Collection Search”. The more volunteers that participate in this project, the more accessible and usable the digital collection will become for everyone.
You can become a contributor in two ways:
Take on a “challenge” of images put together by experts at LAC
Use the new Collection Search to find materials that matter most to you, then enhance them. Anyone can now contribute to digitized images that are found while doing research.
The volunteer must register and create a user account so you can keep track of the records to which you have contributed. Once this free account is established, a volunteer can contribute as much or as little as they would like.
The “Challenges” are content put together under a theme. For instance, under the “Challenges” tab on the website you could choose to transcribe the “Correspondence between Sir Robert Borden and Sir Sam Hughes” The theme for this challenge is listed as “military heritage.”
Or another “Challenge” someone might choose could be “New France and Indigenous Relations” whose theme is listed as “Aboriginal Heritage.”
There are also new “Challenges” being posted to the site, so check back often.
Maybe you would like to contribute using Collection Search. The website describes how this tool works: “When you are conducting research using our new search tool and find images, you’ll see that you have the option to enable this image for Co-Lab contributions. After answering just a few short questions, you can enable an image found in Collection Search for Co-Lab use and transcribe/translate/tag/describe to your heart’s content.”
There is a short tutorial to get you started and show you the ropes. The launch of Co-Lab also introduces a new image viewer, which allows you to zoom in on different parts of the image or move around the image itself. This tool is useful when transcribing or adding keywords and image tags to describe all the small details. Every image in Co-Lab is subject to review by other members. If something is found to be incorrect or if you find something that is wrong, it can be marked as “Needs Review” for others to take another look and decide what is correct.
The best part about this new Library and Archives Canada tool is that every contribution by the volunteers benefits fellow genealogy researchers and improves records access. Every additional tag or translation becomes new metadata and is searchable within 24 hours of the transcriptions or tagging being done.
So, if you are like me and are eager to get as much genealogical and historical records online and transcribed, check into The Library and Archives of Canada’s new Co-Laband Collection Search!

Sears Catalog Fall 1960, Cover. Digital image from Ancestry.com. Historic Catalogs of Sears, Roebuck and Co., 1896-1993 [database on-line]. Provo, UT, USA: Ancestry.com Operations, Inc., 2010. Original data: Sears Roebuck Catalogs 1896–1993. Vol.102–228 K. Chicago, Illinois: Sears, Roebuck and Co.
Back in “the day,” American consumers window-shopped by mail with the Sears catalog. From 1888-1993, the Sears catalog stocked millions of American households and fed the Christmas lists of men, women and children.
Wouldn’t pages from the Sears catalog make a lively addition to your family history posts, pins, pages and conversations? Ancestry.com thinks so, too! They’ve digitized the catalogs and they’re keyword-searchablehere. (Just a word of advice: browse a certain issue or search for a specific product. A keyword search for “bicycle” brings up over 5000 results through the OCR technology used to find matches.)
According to this brief history, the Sears catalog first launched as a mailer for watches and jewelry in 1888. “The time was right for mail order merchandise,” says the article. “Fueled by the Homestead Act of 1862, America’s westward expansion followed the growth of the railroads. The postal system aided the mail order business by permitting the classification of mail order publications as aids in the dissemination of knowledge entitling these catalogs the postage rate of one cent per pound. The advent of Rural Free Delivery in 1896 also made distribution of the catalog economical.”
