1/4 Italian (Sicilian)
3/4 Eastern European Jewish (Russian, Latvian, Polish), the latter has a German last name so likely ancestry to Germany but can't confirm.
BTW, how are we distinguishing between ethnicity and ancestry?
Good question.
While my ancestors came from Ireland, Scotland, Norway, Sweden, France, Wales, England, and Germany.. the vast majority of my ethnicity could be traced to Scotland and Norway.
There is significant Norwegian blood in the Scottish line and significant Scottish blood in the Irish line (the men came from Scotland and married local Irish women).
I guess it just depends on how far back you want to go.
