I'm trying to connect my GG grandmother Mary Ann "Mollie" Boyd Nickell. She was born 12 June 1849, I believe in Caldwell County, KY. She died 1 Sept 1936 in Livingston County, KY. She was the daugther of Joseph and Malinda Chandler Boyd. She married Madison Criswell "Matt" Nickell. I notice on the 1870 census, Malinda and her daughters Lucinda and Mildred were living with Mary Ann and Madison. No mention of Joseph. I'm wondering if maybe he died in the Civil War? Anybody know?
