DNA PROGRAMS FOR GENEOLOGY
Personally, I used Ancestry.Com DNA and received the results of ethnicity citing the Iberian Peninsula, Greek Italian, Irish, North African, Native American, etc. I did not expect such a diversity. Discussion with various entities suggests it is consistent with the occupants of Europe over many centuries.
I also used the Family Tree DNA and keep getting new relatives found. Most of them are somewhat distant. Still trying to get a handle on how to use this in further developing my tree. As of this week, there were over 3000 possible relatives. Wow!
