tullahy
Tullahy is a surname of Irish origin. It is believed to be an anglicized form of the Gaelic name Ó Tuathail, which translates to "descendant of Tuathal." Tuathal itself is a personal name meaning "powerful ruler" or "chief of the people." The surname is most commonly found in the province of Leinster, particularly in the counties of Kildare and Dublin. Historically, the Ó Tuathail clan was a prominent Gaelic family in this region, holding significant land and influence.
Over time, as with many Irish surnames, variations in spelling emerged due to anglicization and phonetic interpretations.
