Frederick Sears Grand d'Hauteville

He and two Harvard classmates toured England, Ireland, and Scotland after graduation in July 1859. He was appointed volunteer aide-de-camp (ADC) to General Nathaniel Banks in December 1861, and was in action with him at Winchester in 1862. He was commissioned Captain and Assistant Adjutant General of Volunteers on 30 June 1862. He then served on General Samuel Crawford's staff, including in action at Cedar Mountain in August.

In his Report, General Crawford said:

... Of my staff officers, I desire to mention Captain Frederick d'Hauteville, my assistant adjutant-general, who was indefatigable in rendering me the most important services on the field...

He was back with General Banks, as ADC, in the Department of the Gulf by December 1862. He resigned his commission on 24 February 1863.

He was a member of the Union Club of New York by 1867, and was a charter member of the Newport (RI) Yacht Racing Association in 1901.

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.

His father's family auctioned historical items - including Frederick's uniforms - from the ancestral castle on Lake Geneva, Switzerland in 2015. See a YouTube video describing the castle and contents, source also of his picture above.
