My Mom (Winifred maiden name Swallow) and I are looking for information about John M. Swallow born in Delaware circa 1795. He married Martha Van Matre December 28, 1820 in Green County, PA. He died March of 1843 and is buried in Letart Falls, Meigs County Ohio. I do not know his parents names, however his children's names are Sarah Ann, Hiram Heaton, Mary Elizabeth, William Merchant, Martha, and Priscilla. Could your William be the brother of my John M.? Have you any dates to help make the connection?
