Looking for Silas H Catlin Michigan

Silas H. Catlin (father Nathanial) of Michigan married my great-grandmother, Helen Augusta Lynts in 1865 in Janesville, WI., then in the 1870 Census of Michigan. I don't know anymore than that until I found she married my great-grandfather in 1878 in Fulton/Edgerton, Rock County, Wisconsin.
I am seeking information as to her life during 1865/1870 and if there were any children.
Thank you,
Karen Martinsen
