I found a second cousin once removed on my Eley side on MyHeritage. I’ve not used Ancestry’s DNA tools yet but I imagine that this is similar to Thrulines. On MyHeritage this feature is called Theory of Family Relativity™. Note that they used another person’s tree to link mine to my cousin.

Her grandfather and my great grandfather were brothers. Her parent is the first cousin of my grandmother. And she is second cousins with my parent. We have exchanged messages and confirmed this.

(I’ve redacted some information because even though I’m sharing my business, I’m not trying to share all my business or that of my new cousin.)

One great thing about locating close cousins is that you can isolate which segments of DNA go with which family line. Here’s an example.

This will help you identify other matches on that same line.

I’m no genetic genealogist but I learned how to do this from one. Check out Quincy Gossfield at https://dnadetangled.thinkific.com/courses/gedmatch-101
