I wonder, were/are your Friedman Family from Munkachevo -Kohanim or Yisroel?
Do you have any 'other' family info?
I am a nee Friedman, so was My late Mother-in law.
To my knowledge, my late mother-in law's grandfather was Dayan Zvi- Hakoheb Friedman--Dayan of Beregovo/ Kezmark ?
I wonder, what is written on his -Abraham Friedman's Matzevah?
