Rita Rubsam Dolan was my grandmother.
Her father was Joseph Rubsam who married Sarah Dewey. She had two sisters Sadie and Mary; Sadie had a daughter named Dorothy who had a daughter named Denise and I'm not sure about Mary's children.
She married James Dolan in 1933; he was the Chief Engineer of Richmond Memorial Hospital (now Staten Island University Hospital). They took in and raised many children from Catholic Charities; your grandmother Nancy grew up in the house with my mother Mary, the both of them passed away in 1974.
Your father, William (Billy), is my cousin.
