Gworks is a tool at DNAGedcom.com that quickly generates surname lists using information from your DNA matches’ trees. I have found this to be an efficient and valuable tool when seeking an unknown ancestor. When paired with a network graph it becomes very powerful. Gworks and a Network graph work...
When you hear the term endogamy, what communities come to mind? French Canadians, Puerto Ricians, Mennonites, Pacific Islanders, and Ashkenazi Jews are common examples. Some of these examples are from island peoples, so what about the Irish? Last time, I discussed the effect of a clearly endogamous community, Ashkenazi Jewish...
As genealogists we want to understand our match lists. We want to identify the matches that will give us the solid clues we need to make progress on our target ancestor’s family tree. Endogamy and its close cousins, pedigree collapse and multiple relationships, complicates that. Diana laid out the definitions...
Can segment patterns help you differentiate matches with paternal grandparent from a maternal grandparent? A tool at DNA Painter helps you do just that. The tool is called Library of Matches – https://dnapainter.com/tools/lom, developed by Cody Ely. In a blog post titled “Introducing the Library of Matches,” from May 2022,...
Have you ever suspected that endogamy was affecting your DNA analysis? You might notice a large number of matches from an island population or isolated area. The matches might seem to share a lot of DNA but no common ancestor can be determined. Clustering matches doesn’t seem to produce clusters...
Steve Little, one of our Research Like a Pro with DNA 4 Study Group members, wrote this guest blog post about how he uses diagrams to help visualize the multiple relationships with his DNA matches. He is from a community of mild endogamy — Appalachia. I hope his insights will...
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...
Pedigree collapse occurs in a person’s family tree if one of their ancestral couples are related to each other. This causes the same ancestors to be repeated in their tree. For example, if a person’s parents are second cousins through their great-grandparents Joseph Dyer and Anna Smith, then Joseph Dyer...
