"Privates and twin brothers Bartlett and John Ellsworth with brother Samuel Ellsworth of Company A, 12th New Hampshire Infantry"
The brothers Ellsworth were all born and living in Wentworth, Grafton County, New Hampshire when the call for 300,000 troops went out in July 1862. The 12th NH Infantry was quickly raised, primarily in Belknap County, beginning in August, with neighboring towns of other counties adding their volunteers. The town of Wentworth contributed 27 men to the 12th NH, 8 of those having the surname Ellsworth. Four of them went into Co. A, while the others were assigned to Co. K.
