Looking for ? Hopp who worked in post office (Sopot?) 1930's daughter was Charlotte Hopp who married Franz Rogotzki. My father was their son born 1925 in Langfuhr, Guenther Rogotzki. He is still alive. He went to Volk Schule, Fuer Knaben, schwalben gasse. Any help will be VERY much appreciated. We live in England & want to look at my fathers side of the family tree. Sorry my dad's memory is. Very poor & I cannot speak polish.
