US Navy and Marine Corps Registries indicate that "J.C. Wentworth" served from 1862-1865, though it appears he first enlisted in Boston in 1861. The USS Daffodil was a converted side-wheeler steamer armed with 2 20-pdr. rifles and a crew of 35.  She joined the South Atlantic Blockading Squadron in December 1862 and remained at the Port Royal, SC station for the duration of the war.  Daffodil served largely as a tug, occasionally engaged in riverine reconnaissance forays along the South Carolina and Georgia coast.  She was sold out of service in 1867.

See also Lot 336, the letter archive of Nathan W. Curial, Co. A, 8th Minnesota Regiment. Wentworth's letters and CDV were acquired with items related to Nathan Curial. Wentworth's mother was Eliza T. Currial [sic] Wentworth (1817-1887), who was likely a sister of Nathan Curial and Rachel Curial Banton. Eliza's last name is alternately recorded as LaCurial.
