I'm trying to find out more (eg death date, children perhaps from 2nd marriage) about Mary Blackford dtr of Benjamin who was from Frederick Co MD, owned Isabella Furnace near Luray, Shenandoah Co, by 1812 with J. Arthur. Mary married 1) Joseph Manley Lauck of Winchester VA in 1825, one child, he d.1829, she md 2) James Arthur, possibly a son of Benj Blackford's business partner. He seems to have died 1853 but can't find any more about Mary. Appreciate any help.
