Owen was married to Sarah O'Brian, moved to Manchester, PA, which is the Old North Side of Pittsburgh, Pa from County Clare. It was recorded that Sarah had 15 children, but the ones we know of are: John (1863) Matthew (1865) Mary, Sarah and Nell. My branch of the family is descended from Matthew, as follows:
Matthew married Mary Delaney of Philadelphia, producing (among others) Joseph Aloysius (1889).
Joseph married Margaret Grounds and lived in Pittsburgh, Pa. producing 10 children (she died in childbirth of the 11th).
Joseph Eugene is my father.
Please reply with how you are connected.
I look forward to hearing from you.
