You’re missing about half of your real 4th cousins in your DNA match list! This short video tutorial explains why aren’t they showing up on your DNA match list if they’ve tested at the same company!

DNA testing is a powerful tool for finding genetic relatives who don’t show up on your pedigree chart—and for being introduced to genetic relatives who are on your tree but who you don’t know personally. As I’ve said in a previous article, you may have to weed through hundreds of matches in, say, the 4th cousin range, to identify your actual 4th cousins, so matching doesn’t necessarily serve you up fully-identified relatives on a silver platter.

Here’s another twist for you. Many of your actual 4th cousins may be missing from your DNA match list, even if they have tested on the same site you have! This sometimes confuses people. Here’s a short video tutorial clip showing how this is the case:

That’s worth saying again. DNA is increasingly able to serve as a powerful genealogical tool to help you identify unknown ancestors (or confirm the identities of not-quite-sure ancestors).

    Wow, I have been ignoring anything past 3rd cousins right now til I get a grasp of labeling and splitting. I will have to go back and add these. I have just too many right now, blessing yes, but cumbersome for sure

    I love the enthusiasm that Diahan has for researching with DNA. I have the book and I listen to her every chance I get. She helps people feel good about researching and does not make anyone feel like a failure. I am in the process of moving so I can not commit to doing the workshop now. But in the meantime, I am still in touch with some of my 4th cousins and working to solve a DNA connections mystery which I have worked on for more than 5 years. Thanks for all the informative and encouraging emails.
