I'm looking for ancestors from Marmorossziget,
I know the following
Yitzchak Meir Frenkel / ?
Moshe Frenkel / Frimat Davidovits
Eliyahu Frenkel / Frieda Wieder
Shlomo Dov (Ber) Wieder / Zisel Kovacs (parents of Frieda)
There are all supposed to have been born in Marmorossziget
Frenkel may be spelled as Frankel with an a umlaut.
Wieder may also have been spelled as Vieder
