Ehrenpreis Genealogy

All Ehrenpreises are related, or are we? It appears that Ehrenpreis is an extremely rare
last name. I have found only a handful of family trees with that name:
Family#1- those descendants of Solomon Ehrenpreis(my great-grandfather who came
from Poland to New York,(see FTM vol. 25 tree 1150)
Family#2-those descendants of Fanny(Pearl?)Ehrenpreis, who came from Lemberg,
Galicia to Baltimore (see FTM vol. 2 tree 2782 & FTM vol. 5 tree 2831,
Family#3-those descendants of Sabina (Babbe)Sprintze Ehrenpreis, who came from
Lemberg, some settling in Sweden and some in the USA (including Marcus Ehrenpreis,
the one time Chief Rabbi of Sweden,
Family#4-those related to the brothers William & Joseph, who settled in New York City,
Family#5-those related to an Adolf Ehrenpreis who continued to live in Germany.
Family#6-those who spell the name Ehrinpreis, Ehrinpries
I am certain there are also an additional 1 or 2 families of which I am presently
unaware.
With only a handful of families of Ehrenpreis, many originating from the same general
area of Europe it seems reasonable that we are all cousins.
