Have you come across a Rebecca DUCK, born between 1800-1810 and died 1 Aug 1849? She was the second wife of Ephraim SWANGER whom she married between 1838-1840. They had one child that I know of, Caroline Agnes SWANGER, born 7 Aug 1844. This is not my direct line as I descend from a child of Ephraim's first marriage to Sarah HOWELL, but information of the second wife might lead to something helpful. Thanks. Betty
