Would you like an efficient method to find clusters of DNA matches relevant to your research subject? In this series, I’m sharing the steps to create a network graph using the free, open source Gephi application, available for Windows or Mac. I use Gephi to create network graphs of my AncestryDNA matches, but you can use matches from other companies as well. Throughout this series, I will be using my own matches from AncestryDNA, but I have changed their names for privacy. To see the first step in this tutorial, go here: Creating Gephi Network Graphs Part 1: Gather Matches...
I am sure I am not alone in finding that I constantly have more to learn when it comes to using DNA in my genealogy research. For example, I have defined many situations in my DNA research as pedigree collapse. However, after reading Diana’s post Endogamy, Pedigree Collapse, and Multiple Relationships: What’s the Difference and Why Does it Matter? I realized that almost always, when I used the term pedigree collapse, I was actually describing multiple relationships. Diana defines both pedigree collapse and multiple relationships in her post: “Pedigree collapse occurs when cousins reproduce, and their descendants have ancestors in...
Did you participate in Y-DNA testing before the era of FamilyTree DNA and now have no access to your results? If so, let me introduce you to mitoYDNA.org, a free website where you can recreate the kits used in the project. MitoYDNA.org allows uploading or manually adding your Y-DNA or mitochondrial (mt) DNA test results from several testing companies. You can then use the mitoYDNA tools to compare kits and find matches. You’ll likely recognize FamilyTreeDNA as the current big player in mtDNA and Y-DNA testing, but several others are currently testing or performed tests in the past. Among the...
X-DNA has a unique inheritance pattern, and knowing about it can sometimes help you figure out the ancestors you share with a DNA match. Men inherit a Y chromosome from their father, and an X chromosome from their mother. It is easy to imagine that an X chromosome remains unchanged just like a Y chromosome does when it is passed from father to son, but this is not the case with X-DNA. Here is a question from someone in the Research Like a Pro with DNA study group: “This is how my X chromosome compares with my brother’s on 23andme....
When you start a family history research project and want to incorporate Family Tree DNA test results in the search for your ancestors, I have a hot tip for you! Use the AutoTree tool at Genetic Affairs. I recommend you use it at the beginning of the research project. The AutoTree report gives you a headstart on grouping your DNA matches in clusters of related individuals, connecting their family trees, and it gives you concise data that you can use in connecting DNA matches with your shared ancestors. There are too many important elements in the AutoTree report...
Do you sometimes feel frustrated as you try to sort out the connections between DNA matches and shared ancestors? I do, and I think we all need help with this from time to time. The AutoKinship tool at GeneticAffairs.com can quickly offer possible solutions to the problem. AutoKinship can help you construct a family tree of DNA matches from 23andMe that point to shared/common ancestors when there are few clues about who those ancestors are. The tool is similar to the predicted family tree at 23andMe which groups matches by the amount of DNA shared matches share with each other....
In a previous post, I wrote about making a network graph using the RootsFinder triangulation/cluster view with AncestryDNA shared matches. Today, I’m sharing how to make a network graph at RootsFinder with MyHeritage matches. RootsFinder can create a network graph based on segment triangulation, which is a unique feature. You can also create a separate MyHeritage network graph using just shared matches (and no triangulation data). I will show how to do both types of graphs in this post. About RootsFinder RootsFinder, owned by FindMyPast, is a family tree building and DNA analysis website. The premium level allows the use...
No, it’s not a game show or a board game – it’s a fantastic tool in the hands of serious genetic genealogy researchers! What are the Odds? (WATO) is a tool developed by Leah Larkin, and Jonny Perl at DNAPainter.com. You can use this tool to further your research in cases where you don’t know how a person fits into a family tree, such as in adoption or unknown parentage research cases. It can also be used as a sanity check when building a family tree to help you see if you have placed a DNA match into the correct...
