One of the three daughters I believe was named Nancy. John's wife appears to have died in the 1820s. Both John and his wife appear to have been born in the 1770s. According to the 1880 census Groves father is listed as born in Virginia. I believe they were married in Franklin County, Tennessee.
Franklin County has no marriage records for that time period.
Elijah, Betty and Ryal moved to Alabama in 1830 or 1831. I do not know when they came to DeKalb County, in 1830 and 1831 it was still part of the Cherokee Nation. It is possible that these could have been Betty's family and may have been what brought them to the DeKalb County area. Nevertheless Elijah is listed in the 1840 Census of DeKalb County and lived in Will's Valley area near Lebanon. According to Alabama Land Records he was granted the land patent of 159.4 acres on May 01, 1845.
