Drake, Sorry I can't help you on Calvin's parents, but maybe you can help me. Do you have his children's names and birthdates?I know he md Martha Eugenia Lane (b 16 Jun 1835) who was the dau of William Henry Lane and Elizabeth Pepper Garner, and I have quite a bit of info on their family if you want it.
Calvin & Martha were md 5 Feb 1856 in Hinds Co, and in 1870 they were in the Hinds Co census with children William, Florance, Walter, and Laura M., plus Green Williams, the son of Martha's sister Mary Lucy.I can't find them in 1880, but in the 1900 census of Burleson Co, TX, (Pct 5) I found #159 Cal Adams, b Jul 1833 in MS, with wife MARY E. [Is this a second wife???] b May 1834 MS and a son Forest H, b Feb 1873 MS.Is this them?I'm not sure.
My notes say Martha Eugenia died in Burleson Co on 16 Feb 1906, but that's not set in stone.Do you know when Calvin died?
The Texas Death Index lists a Mary Adams, d Burleson Co on 17 Jul 1903, and a Calvin Spence Adams, d Burleson Co 10 May 1934.I don't know who these are.
