References & notes

Service data from Heitman1. Details from family genealogists. His gravesite is on Findagrave. His father was Paul Daniel Gonzalve Grand d'Hauteville of Switzerland and his mother was Ellen Sears, of Boston.

Frederick was the subject of a habeus corpus case brought by his father in 1840 after his mother left him in Switerland and returned to Boston where she had her son. The case is widely cited in the literature about family law of the period. Frederick married Elizabeth Stuyvesant Fish (daughter of Hamilton Fish of New York) in 1863, but she died in 1864. He married Susan Watts Macomb (granddaughter of General Alexander Macomb) in 1872. An 1895 portrait of her is in the New York Historical Society Museum.
