Yes. About two years ago we connected with another family related to me by an in-law. It's been a most happy connection and we like each other very much and have grown close. It's really amazing.
So I did my own DNA, and there is no surprise on my genetic makeup, except for more Irish than Scottish. But wow, there is an abundance of 3-4th cousins that we can't figure out where they come from. I haven't had time to connect with them. But we built a family tree a few years ago and it was fascinating. One of the things that affected me emotionally was how many babies people had, and how many they lost, and how short the lifespan was.
I think it's a great service. Thank you Mormons.
