Papke is Alfred E. Papke from Milwaukee, Wisconsin USA. I do not know his father's name, but his father was a renowned decorative plasterer in Milwaukee, Wisconsin.
Alfred E. Papke had a sister named Anna H. Papke Strelke (1884-1988) and a brother named Henry J. Papke (1879-1960).
He married Lillian E. Brandt (1895-1985) and they had three daughters: Anita Papke Schroeder, Verna Papke Ebert [my mother] and Averyl Papke Mensching.
My mother (Verna) died just before I turned 5 years old and that is why I do not have a lot of information about the Papke's or the Brandt's.
