Hello Yael 29th June 2022
I am a nee Friedman ( daughter of Mor/Moishe Friedman)
and researching my Friedman Family--descendants--of Herman Friedman--USA
and descendant of my Friedman family --prior to arriving to the USA?
I would like to add--that my Friedman Family--are 'Yisroel'
I am also researching my Husband's mother's Friedman family
Izsak/Yitchok Friedman--OZD---Hungary--(Paloc Beregszasz-- etc.) --before the War
Many descendants resides in the USA and Israel,
Some remains in Eastern Europe
I would like to add-that my Mother-in Laws Friedman Family are Kohanim
You mention -secular names--Arthur; Herbert; Irving:
I wonder what was their Jewish name?
Where are they buried?
To my knowledge--their father's name are often on the Matzevah
Which is a significant--pathway.
