I am looking for anyone who would have knowledge of the following family:

William L. M. Wensel born 1825 and wife Margaret Smith born 1828. Both are from Pennsylvania. The moved to Logan Twp, Marshall County, Iowa ca 1866.

Their children are:
George W Wensel
Franklin Jefferson Wensel
Lewis C Wensel
Flora Wensel
Charles Wensel
Catherine "Kate" Wensel

I am most interested in Franklin Jefferson Wensel who married Sarah M Walker.
