The 1870 New York census shows a Samuel Gray, aged 40, married to a Margaret, aged 36, with a mother also called Margaret, aged 70, all from Ireland, and with children, the oldest aged 18 and all born in New York. It is possible that this is him emigrating aged only 22. He has a brother George, which is NOT a Gray name but he also has a daughter, Isabella, which IS a Gray name.
