Patrick, who do you descend from in this family? My great, great grandfather was John Devlin from Ireland who married Margaret MacIntyre. He could have been born as late as 1858 (would have been only 17 when my great grandma was born). They had children with names similar to your John Devlin's siblings-Mary, David, Jane, Sarah, Elizabeth, and Margaret. Jane married a Mr. Matthews. Do you know if you are related to this family who settled in Pennsylvania and New Jersey?
