I am seeking information on the ancestors or parents and siblings of Frances Ann DUNHAM or Frances Ann DUNNAM who married John ADDISON on 4 December 1811, probably in South Carolina. They had no children. They were on an ocean voyage and were lost at sea in December 1812.

John ADDISON's father was also John ADDISON, so I shall henceforth refer to the younger as Jr. and the elder as Capt. to avoid confusion.

The father of John ADDISON, Jr. was Capt. John ADDISON, a mariner. The ADDISON family resided in Georgetown County, South Carolina.

Capt. John ADDISON was in Charleston, SC prior to removing to Georgetown.

In 1784 in Charleston, SC, Capt. John ADDISON married Tamson RALPH, daughter of John RALPH and his first wife, Ann.

Have any of you DUNNAM/DUNNHAM lost track of a Frances DUNNAM /DUNHAM who might be this one?
