And....

Our friend Algernon Sydney Cabell was the son-in-law of Col. DeRosey Carroll of Pierce's "Division" of Arkansas State Troops confusingly called the 1st Arkansas Cavalry and also the 3rd Arkansas Cavalry -- confusing since there are multiple units with the same designations. Col Carroll was murdered by "jayhawkers" (from Arkansas, not Kansas) in 1863.

"A dispatch came from Russellville that De Rosey Carroll had been murdered in Franklin county by the jayhawkers, under the command of Bill Dark, a former inmate of our penitentiary." True Democrat, [Little Rock, Arkansas], January 21, 1863, page 1, column 1.

"It was reported that Parks, the renegade Texan, who, at the head of a band of jayhawkers had murdered De Rosey Carroll, had been caught and was to be sent here [Little Rock]; also, that Bill Dark had been wounded and taken prisoner." True Democrat, January 28, 1863, page 1, column 1.

A.S. Cabell's son was Maj Gen DeRosey Carroll Cabell, born in Ft Smith AR, July 7, 1861:

"Born at Fort Smith, Arkansas, the son and first child of a Confederate officer, Major Algernon Sydney Cabell, and Mary Angella Carroll. He was named after his mother's father, a Colonel in the Confederate Army."
