Hi Al, I think you may have misread the other message, I believe Jane was born in about 1770. I have no real proof of that, but other dates seem to add up to about that. Below is a paste from the information I have gathered.
Generation No. 1
1. JAMES1 ADAMS died bet. 1820-1830. He married JANE b. Abt. 1770.
More about JAMES ADAMS: Census: 1820 Louisa County, listed with wife JANE and 11 children, one under 10 (JAMES JR?)
More about JANE: Census 1: 1830 Louisa County, listed as 60-69, with at least 1 male, 15-19 (JAMES JR?); 1 female, 15-19; and 3 females, 20-29. Census 2: 1840 Louisa County, listed widowed, 70-79, with at least 1female, 29-29, and 2 females 30-39.
Children of JAMES ADAMS and JANE are (at least): 2. i.JAMES M.2 ADAMS Jr, b. Abt. 1815, Goochland, VA; d. March 9, 1872, Fluvanna County VA. ii.GEORGE ADAMS iiiWILLIAM ADAMS This is all I have on them. Any help is appreciated. Thanks so much!!
