Erroll \e-rro-ll\ as a boy's name is pronounced AIR-ul. Possibly a variant of Earl, or may linked to the Latin "errare", meaning "to wander". May also derive from a Scottish place name; there have been Scottish Earls of Erroll for more than 600 years. Made familiar in the 1930s due to Errol Flynn, famous for his swashbuckling roles.
Erroll has 5 variant forms: Errol, Erryl, Erryle, Eryle and Rollo.
