I have William M. F. Gembler b. ca 1854 married to Wilhelmina Jacob b. ca 1855, with the 1900 census showing they were married ca 1876. The above marriage was witnessed by A. F. Jacob who I think to be a brother of Wilhelmina. Is the license referenced in the subject line for this couple? Is the Johnson surname a clerical error or what? As many William/Wilhelm Gemblers as I have, can't find one to marry Mina Johnson/Janszen, etal. Only one I have in the possibly correct age range is WMF who married Wilhelmina Jacob. Again, hoping someone more familiar with this clan can straighten out this old lady!!!
