Jacob Wagoner married Martha Underwood 1861 Marion Co., IN

Looking for information on a Jacob Wagoner who married a Martha Underwood in 1861, Marion County, Indiana.I haven't been able to locate him in the census records.

Martha was married to William Ruley in 1856 before Jacob, and they must have divorced.There are a bunch of kids listed in these mixed families, and I'm having difficulty determining which kids go with which families.Any help would be appreciated!
