toolan

Toolan refers to a surname of Irish origin. It is an anglicized form of the Gaelic Ó Tuathaláin, meaning "descendant of Tuathalán". Tuathalán itself is derived from the Irish personal name Tuathal, which means "chiefly strong" or "strong ruler". The Tuathaláin clan was historically prominent in the province of Connacht, particularly in the region that is now County Leitrim. The name is relatively uncommon but can be found in various English-speaking countries, with a notable presence in Ireland and the United States. Variations in spelling may exist due to historical transcription practices. The surname is associated with a lineage of chieftains and notable individuals throughout Irish history.
