Jacob Keen(e) and Mary Ann Lincoln marriage
I am looking for the marriage record for Jacob Keen(e) and Mary Ann Lincoln about 1845.
Her mother Diana's second marriage and her sister Hannah marriage are reported in the Cass County Michigan Dibean Marriage Index. There is a Mary Ann in 1845 but to a William Johnson.
I don't see them in any surrounding counties either.
Is it possible the William Johnson spouse is in error?
