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 (AJ), on a relatively non-endogamous community, German, within my dad’s match list. My dad has more AJ matches with longer segments (greater than 20 cM),...
Today’s episode of Research Like a Pro is about double cousins. Do you have any? We’ll talk about how double cousins and other relatives with whom you share multiple relationships can affect DNA match analysis and genetic network analysis. Although double 3rd cousins don’t always share an inflated amount of DNA, you can definitely tell they are double cousins in your network analysis. Join us as we discuss these issues. Transcript Nicole (1s): This...
Have you ever used the MyHeritage chromosome browser to view triangulated segments? It’s a wonderful tool. A member of the Research Like a Pro with DNA study group asked a great question about his experience using it. He said, I’ve compared the DNA of 3 people with my mom: Bob, my mom’s 1st cousin on her dad’s side two DNA cousins I’m researching, Jane and Jill (names changed) Bob triangulates with Jane on chromosome...
Segments of DNA that reportedly match can sometimes be pseudosegments, or false segments. These pseudosegments were not inherited from a common ancestor. In this Research Like a Pro with DNA Q&A video, I discuss pseudosegments and share an example of finding a probable pseudosegment with a match at MyHeritage. When creating triangulated groups with MyHeritage matches following Jim Bartlett’s methodology, you can sort overlapping segments into two groups, one for maternal and one for paternal....
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...
Have you heard the term “segment triangulation” associated with DNA and wondered what that meant? Perhaps you wondered if this could help you confirm an ancestor that you’ve researched? Which DNA testing and third-party companies offer this tool? In this article, I’ll define the term and show how the process can help you in your genealogy journey of discovering your genetic family tree. Pedigree Triangulation I previously wrote about pedigree triangulation and used the following visual...
For most of us, the goal of genetic genealogy is to identify how our DNA matches are related to us. We want to determine our common ancestor or identify an ancestor who was previously unknown to us. Chromosome browsers help us do that. By determining that an autosomal DNA segment was inherited from a certain ancestor, we can use that segment information in the future to identify matches whose connection to us is unknown. Chromosome...
Have you taken the Ancestry DNA test and now you’re wondering what to do with your results? Besides viewing your ethnicity estimate, what else can you do to get the most bang for your buck? Today I’ll give you three tips that will get you started on your DNA adventure. TIP #1 Download your Raw Ancestry DNA and Upload to Other Websites Now that you’ve tested with Ancestry DNA, you can take advantage of your...
Are you the lucky recipient of your family’s genealogy? Do you have a box, a barrel, or, in my instance, a suitcase full of letters, documents, photos, family group sheets, etc? You are probably feeling overwhelmed with either joy or despair. Go ahead and be ecstatic that you inherited priceless stuff. Don’t despair because I’m going to show you how to take care of your papers, one step at a time. When I started...
According to D. Joshua Taylor at the Green Valley (AZ) Genealogical Society seminar yesterday, the stereotypical genealogist is a 65 year old white female. He learned this when he dedicated a separate web browser for his genealogy google searches only. Google built a profile based on these searches to target him for advertisements. He found out from friends at google that google thought he was a 65 year old white female. We got a...
