I wonder?? James Curtis Cansler, son of Plinny Cansler did marry a Sylvia Adams. They had ten children. Non were named Nancy Cordelia.I think, the Sylvia that married Drury P. Alexander was a Dunning and her father was Cullen Dunning(1806)and her mother was Anna. They had six other children,all born in the Crofton community.Interesting though, John Medley Cansler and his marriage to Eva Virginia Hamby. More familiar names for this area.I am going to have to do more research on this one!
