Daniel Grimsley (who was characterized as a schoolteacher on the 1860 census but as a farmer on the enlistment roll) joined the same unit as a corporal at Manassas, Virginia, on April 22, 1862.
Following the Battle of Front Royal, although Thomas would remain a private for the rest of the war, Daniel was promoted to sergeant on June 20, 1862.
[4] After the war, Grimsley read law under commonwealth attorney Horatio G. Moffet (1808–1892) of Rappahannock County, Virginia.
Following admission to the Virginia bar, Grimsley moved to Culpeper and practiced law with James Barbour.
Not long afterward, fellow legislators elected him a judge of the Circuit Court in Culpeper, so his longtime law partner (and later in-law) James Barbour resumed the seat he had held before the American Civil War.
