My paternal line's dna signature is rare--J2a-Eta (m92+)--the Griese surname, in its variations, are primarily Italian--Grisi, Grieco, Greco--but my people are from Germany--the only match I had was someone in Alsace France--many Italians and Jewish people settled here going way back--I'm now aware of my Greek heritage, but were my paternal ancestors possibly Greek Jews from southern Italy?--any info is good info--Kevin
