Forums Geneanet

After many years of being on YSearch and FTDNA , I have no matches. Now I am branching out and hope that someone will test the same as I.  Does anyone have a line on European databases  that I can compare to?

My earliest ancestor is identified in 1645 and living in a small village near Rhinau, Alsace, south of Strasbourg.
I very much would like someone in Europe to tell me how to get information on ADN there.
Thank you very much
