Judith Singer asked about the father of Abraham and Benjamin Singer.
He was Rabbi Pesach aka Fulop Singer (umlaut over the u in Fulop), b. in 1816
in Uhersky Brod (now in the Czech Republic), d. 1898, buried in Spisske
Podhradie (now in Slovakia).
He was rabbi of rabbi of Varpalota (1847-187?) then Kirchdorf aka Szepesujfalu
His wife was Chaye Feigele Halevy Loewy. Her grandfather was Benjamin Wolf Loew.
So Abraham and Benjamin were the latter's great-grandsons.
