Darol is of American origin, derived from the Irish surname O'Doran which means 'descendant of Doran'. It was initially used as a given name during the mid-20th century in the United States.
It appears the name Darol was quite popular from the late 1920s to the mid-1950s, with the highest number of births occurring in 1936 (18 births) and 1952 (16 births). However, it seems this popularity waned over time, as there were only five births each in 1995 and 1967.
