Robert (53) Emmet was the middle brother, sons of Catherine Elizabeth James (Kitty) and Robert Emmet. He was born in New York at 10 Waverly Place on the 30th of September, 1850, only 13 months after the birth of his older brother, William Augustus. His mother died when he was 7 years old and his father died before he turned 20. The children seem to have moved with their father to New Rochelle in Westchester county when their mother died, and then probably to live with one of their uncles when the father died in 1870. Robert went to Columbia, studied law, and graduated in 1876, but he died less than ten years later on the 14th of January, 1884.
