Many thanks Mirek! Unfortunately, the same can not specify the place of residence of them. I was told of two German archives about him no information. I can only assume that the remaining cities in the first place to see the records from Bogucice, because there is one of the oldest churches and is located almost in the center of Katowice. Maybe they were only recorded in the church books, but not in the civil register of births? And maybe it can help to specify the place: one of the daughters of Richard Sculz left behind an unusual Catholic pectoral cross, made of black stone, it seems hexagonal (or tetrahedral) in cross section.
