He had the following siblings Robert,Mary,Walter,and the following half brothers and sisters Raymond, Catherine and Hildagarde. His parents where Patrick McNamara and Margaret(nee)Toomey. William last lived in Palm Springs,Ca. I would also like to findout what he did for a living. When his father passed away in 1930 William was living in Cincinnati,Ohio.
