I just sent in the saliva sample to the Ancestry.com DNA project. I'm not sure how specific the results are but I'm very curious for the results.

I do have ancestors from England, Ireland and Germany. You can make your results public on Ancestry.com and they will match you with others. At least that's what I'm told. I do have a feeling that my English & Irish will be lumped together as British Isles and the German as Central Eurpoean. It would be great to find other data bases to share and compare my results.
