Apologies for not including dates! I know better. Louis was born ABT 1836 in Prussia. Acc. to 1870 census,dau. Emma (1) was born in IL & Chas (4 mos) born in IA. So they came to Ft. Madison in 1869. In 1880 census, they had added Caroline (ABT 1872) & William (1878). William's son Paul E. PASSER was born 3 Oct 1920 & died 7 May 2002.Paul's son Randall W. PASSER was born 3 Nov 1954 & died 15 Oct 1987. I do not know any of the surnames of the wives of Louis, William or Paul.
