Genteically. Ashkenazim seem to come from a 100 of _men_. Does not mean that just 100 of them travelled up to Europe, just that only descendants of a 100 survived. True sephardim – from Sefarad – settled from Amsterdam to Turkey after expulsion. joining local communities. I presume everyone from Mediterranean is partly true Sephardi. Not Iraqi/Iranians, Teimani.
