Dervla and Derval are female Irish given names, anglicised from Deirbhile and Dearbhail respectively. Dearbhla is a Gaelicised hybrid of the two names. Deirbhile means "daughter of the fili [poet]". Dearbháil, a common medieval name, may mean "daughter of Fál", Fál being a poetic name for Ireland; or else "true desire".
