Dolan is an Irish surname that originated from the anglicization of the Gaelic patronymic Ó Dubhshláin, meaning "descendant of Dubhshláine." The root name Dubhshláine is derived from Old Irish elements: dub meaning "dark, black" and either slán meaning "challenge, defiance" or the name of the River Slaney (Sláine). Thus, the surname's literal sense ties to a dark or defiant ancestor associated with the river. History and Distribution The surname is primarily found in Ireland. The Ó Dubhshláin sept originated in County Mayo, specifically in the barony of Tirawley. Dolan families have also been recorded in surrounding areas of County Roscommon and County Monaghan. Today, the surname is especially prevalent in Mayo and Dublin, with significant diasporic communities in the United Kingdom, the United States, Canada, and Australia due to Irish emigration.
