My grandmother, Catherine Agnes Duffy, moved to Pittsburgh to be with her extended family after her husband died in 1914. My Dad, Maurice John O'Donnell came to Pittsburgh at the age of 5. He came with his sister, my Aunt Grace, now of Sacramento CA, who was only 3 years old at the time.
My Dad married a relative of his sister's husband, Carl Hauck. Carl Hauck was the son of Mary Kress. Mary Kress' sister, Anna Kress, was my grandmother, the mother of my Mom, Margaret M. Kress. Margaret M Kress married my Dad, Maurice John O'Donnell. My son's name is Shaun Maurice O'Donnell having been named after his great grandfather, John Maurice O'Donnell of Cleveland, Ohio.

I, Hugh O'Donnell, am the grandson of John Maurice O'Donnell
