|J.W. SILLIMAN, CO. C, 1 MINN. CAV.|
Jervis was the youngest of three children by Samuel Silliman and Roxillana Warren. Roxillana was well into her 30's when she and Samuel married, and 43 years old when Jervis was born. Samuel had been married before, and had many children with his first wife. He was 73 when Jervis was born and lived to be 92.
Jervis and his father both served as volunteers in the army. Samuel was about 18 when he first served in the Revolutionary war. He volunteered and served in a number of capacities for the Connecticut Militia in Fairfield, as well as on several ships. One of his commanding officers was a Capt. Jervis. It's possible that it is for that captain that Jervis is named.
Jervis was in his mid-30's when he served in the Civil War, more than 80 years later. Although he was a Mounted Ranger in the 1st Regiment of the Minnesota Cavalry, his service was focused on the Indian Wars, fighting the Sioux Indians who were pushing back against the pioneers settling in the Big Woods of Minnesota.
