Allen, it looks as though your Jesse C. Capshaw was the soldier in Company H, 19th Arkansas Infantry. You noted that he enlisted 03 Mar 1862 at Caney, Arkansas. Caney was a township in Ouachita County. Companies were formed by county, and J.C. appears in the 1860 Census for Caney TWP, Ouachita County, with wife Louisa – I note on Ancestry that her full name was Eliza Louisa (Cannon) Capshaw - and Mary, age 8, was in the household. I note in that census that J.C. was age 40 (born 1820). He was the only Capshaw male of age in Ouachita. Furthermore, Louisa appears as a widow in the 1870 Census for Magazine TWP, Yell County, Arkansas. Members of the household match those in the 1860 census.
