From my mother's research on the Brightwell family, she shows your Jefferson as being the son of Leonard Brightwell and Nancy ?,Leonard Brightwell was born in Virginia and died about 1838 in Meigs Co., TN.No information on Nancy, his wife.He had a brother, William Edward,(b. 12/23/1819 TN, d. 6/3/1872, Ark who was married to Martha Knight, b. 5/30/1819, East TN, d. 8/22/1922, Bell County, Tx.), Gainum, aka Gains, (b.1824, married first time in Meigs Co., TN abt. 1839).Gains was married about four times. He was supposedly well known in Independence Co. and was Captain of Arkansas' bloody 7th infantry in the Civil War. He was considered a hero. Another brother, Elgin, was b. 1822 in TN., d. in Sharp Co., Ark, md. Marye Jane House, b. 1826.They had 13 kids.The Brightwell brothers left TN abt. 1859-61.Deed records showed they sold their land and moved to Arkansas.Jefferson had other siblings, but this is all I have now.
