Tullam

Tullam is a surname of Irish origin. It is believed to be an anglicized form of the Gaelic O'Toole, which translates to "descendant of Tuilealladh." The name Tuilealladh itself is thought to mean "abundance of the world" or "abundance of land."

Historically, the O'Toole clan was a prominent Gaelic Irish family who held considerable power and influence in the medieval Kingdom of Leinster, particularly in the Wicklow Mountains. Their ancestral lands were in the region now known as County Wicklow. The O'Toole chieftains were known for their military prowess and their role in resisting English incursions into Ireland.

As English rule became more established in Ireland, many Gaelic surnames were anglicized, meaning their spelling and pronunciation were altered to sound more English. O'Toole underwent various transformations, with "Tullam" being one of the less common variations. Other common anglicized forms include Tool, Toole, and O'Toole.

Today, individuals bearing the Tullam surname are found in Ireland and in countries with significant Irish diaspora, such as the United States, Canada, Australia, and the United Kingdom. While the direct lineage and historical dominance of the O'Toole clan have faded, the surname Tullam serves as a reminder of a rich and complex Irish heritage. Genealogical research can often trace families with the Tullam surname back to specific regions and historical periods in Ireland.
