He was married to Miss Helen Bennett in St. Louis, Missouri, on September 3, 1856. Helen was the eldest child of William Bennett, a prominent merchant born in Maryland, and his wife Catherine DuBois. They had three known children.
In 1863, Carroll commanded the 1st Brigade, 3rd Division of the II Corps at the Battle of Chancellorsville. During the second day at Gettysburg, his 8th Ohio was involved in skirmishing along the Emmitsburg Road, while the other three regiments of the Gibraltar Brigade, 14th Indiana, Col. John Coons (191)
4th Ohio, Lieut. Col. Leonard W. Carpenter (299)and 7th West Virginia, Lieut. Col. Jonathan H. Lockwood counter-attacked oncoming Confederates from North Carolina and the Louisiana Tigers from Jubal Early's division on the slopes of Cemetery Hill, driving them back in the growing darkness. Carroll later led his depleted brigade in some small engagements during the Mine Run Campaign.
When the war ended, Carroll stayed in the postbellumRegular Army, serving in the inspector general's department. He continued to be affected by his war-time injuries and retired from the army in 1869 with the brevet rank of major general. In August 1886, his wife divorced him.
Death and legacy
In late January 1893, Carroll contracted pneumonia and died six days later at the age of 60 at his country residence, "Belleview", near Takoma Park, Maryland. His death was hastened by his never having fully recovered from his wounds.[dubious – discuss] His funeral was held in St. John's Church in Washington, D.C. He was buried with full military honors in Oak Hill Cemetery in Georgetown, Washington, D.C.[citation needed]
In 1861, Fort Carroll (a.k.a. Battery Carroll), on the edge of Congress Heights in DC was named for him.
The main street in Takoma Park is named Carroll Avenue in his memory.
