I'll send you e-mail and put you in contact with a couple of closer cousins, but here's a bit to start. I can't be absolutely sure that the Hughs are the same; however, thechildren's names make it nearly certain. I have Hugh E. Alexander married to Sarah CALDWELL January 29, 1824, in Blount County, TN; however, many early marriage bonds have names written oddly.
Hugh E. was the youngest son of James Alexander, Jr. and wife Mary, who migrated from Spartanburg County, SC to settle in a part of Roane County, TN, that is now Loudon County. Their graves are just off Highway 321 near Lenoir City, TN.
