Lots of mixes in my family tree I guess I am a bit of a mutt with some cowdog thrown in! DNA

My wife for Christmas gave me a DNA Ancestry kit to find out about my heritage. You send in a sample of your saliva and in 6-8 weeks they give you the results. My parents both grew up in San Antonio, TX and the results and maps show my ancestors from 1775-1925 came from south Texas and the Mexico border area. It was a cool gift and interesting seeing the results. Lots of mixes in my family tree I guess I am a bit of a mutt with some cowdog thrown in!
