Ari = ADONENU Rabbi Itzhak or ELOKI Rabbi Itzhak but certainly not Ashkenazi!!!!
However, the many Ashkenazi/Schinasi/Esquenazi families from the old Ottoman Empire are descendants of migrants from Europe. They have completely assumed local minhagim and are no different from their “Sefardi” neighbors.
There is definitely a conflation of Speyer and shefer/shufra etc to get to Shapiro/Shapira as opposed to Spiro/Spira (same Speyer origin).
What interests me is whether there was a mass emigration from France to No. Africa or whether it was France->Spain->forced migration to North Africa.
