I was adopted. Through Family Tree DNA and Ancestry.com I've found my bio-families both paternal and maternal (the second just recently after a lifetime of searching).

I've been able to trace lines all the way back as far as circa 1000 CE. I've found connections to 27 clans that I can trace back to Scottish soil.

Family Tree can get spendy but the first nibble isn't bad. Ancestry isn't too pricey either. If you're curious, give 'em a shot.
