Searching for Marriage of James HAY and Margaret Elsa STEWARTHello, I am searching for the marriage date and location for James Hay born 1814 in Pittsburgh, Allegheny, PA, and Margaret Elsa Stewart born 1817 in Pittsburgh, Allegheny, PA. James was the son of Robert Hay and Isabella Chambers. Margaret was the daughter of James Vincent Stewart and Catherine Sarah Shaffer. James and Margaret’s oldest child, Isabella C Hay, was born in 1841 in Virginia or Pennsylvania according to census records. James started a boot-tree and last factory in Allegheny in about 1850. I have not been able to locate the family in the 1840 census, but in 1850 they were living in Allegheny City, Allegheny County, PA. Thank you for any helpful information.
