I need to do that. I have a kit, but keep forgetting it.
Careful to read everything included in the “kit” before sending them a sample.
Some of them say that your DNA becomes THEIR property and they can use it any way they want. What if it gets sold to insurance companies or whatever?
Just be careful with whom are sent your “Precious Bodily Fluids”. :-)
I still like the old fashioned way, county records, birth certificates, baptismal records, Journeys of Discovery, and interviews with Elders.
Much more fun than spitting into a tube.
