Looking for information on Louisa Melissa Graves (1852 - 1893.)She married Joseph T. Williams (1844 - ?) abt. 1878. She is one of my wife's maternal great grandmothers. I found a family in the 1870 census of Prairie Twp., Boone Co.This family is headed by Rachel E. Graves age 24. Besides Rachel the family consists of Martha C.; Louisa; William J.; George W.; Alex (Male); and Augustus (female). I think this may be the family I'm looking for but can't prove it. There doesn't seem to be any parents in the family and I have no idea what may have become of them.I have not been able to find this family grouping in the 1860 or 1850 census. I'm also of the opinion that Rachel E.Graves may be the same Rachel Elizabeth who later married a William Ryals. If anyone has any proof that I'm on the right track I would appreciate your help.
