I am trying to figure out who my gr-grandfather's parents & siblings were, & trace his home in Switzerland. He was Peter Paul Steinauer, b. 1850 in Switzerland; immigrated to the U. S. in 1876. In 1900 he was living with his family in Louisville, Ky, running a dairy farm. My grandfather said his dad had several uncles who went out west.
Peter's wife was Anna Catharine Threedouble (LDS has the spelling as Dreydoppel); their marriage record is on familysearch.org, but that's all I can find about her. We have her beautiful portrait.
I'd greatly appreciate any assistance with this research.
