Looking for info on the parents/siblings of Karl Zivitz/Zywietz, b. 12 September 1841 in Klein Schlofken, Konigsberg, East Prussia. Married Fredericka Schmidt (b. 22 September 1849 in Neidenberg, East Prussia) and came to the U.S. (Pittsburgh) in 1885. Karl died 29 September 1915 in Braddock, PA. Any help will be appreciated!
