I have just received a birth certificate from Poland (after much searching) for my father Wladyslaw Derz born 19th Dec 1927 in Smolno, Puck, died in England in 1995. His mother's name is given as Tekla Derz (maiden name Derz) and her address is given as Zelistrzewo, which is nearby. If anyone can suggest where I can go from here, to find out more about Tekla and hopefully Wladyslaw's father, I would be really grateful.
We have always been led to believe that his father was Graf Willhelm August von Belau.
Kind regards.
