My grandfather's name was Harry Pearson Cubbin. He died in Jan. of 1980 and would have been in his late 90's. He lived in Elmhurst Queens and later in Hicksville, NY. He had five children, was a telephone worker. His wife was Dorothy Mohr Cubbin. He was an only child. I believe he was in his late 70's when he died. I am not sure this is the person you are looking for. Please be in touch if this sounds like him and I will contact relatives to attempt to assist you. My mother is his daughter, though she has late stage dementia, not a reliable source. His mother's name was Florence.
