I don't know if this will help you or not but, my husbands grandmother Christine Devlin, had a sister that lived in Woonsocket, RI. Her name was Gertrude Devlin-O'Neil.....Patrick may have been one of their relatives that also moved to RI.
Christine and Gertrude's family were from Fall River, Mass. area
Christine and Gertrude also had a sister name Mary Devlin and a brother James Joseph Devlin.
