Carroll was the second of four sons born to Daniel Carroll of Aghagurty and Littermurna (c. 1642–1688), a Catholic Irishman whose family lost much of their land and wealth in the English Civil War. The exact place of his birth is unclear, though it likely occurred near the small town of Aghagurty that Carroll's father took as part of his name.[1] Some of the family property near Aghagurty was obtained by a friend, Richard Grace, who made Daniel Carroll the head tenant.
