Nualláin

Nualláin is an Irish surname, derived from the Gaelic personal name Nuallán. The name itself is thought to mean "little wolf" or "famous wolf." It is believed to be a diminutive form of the Old Irish word "faol" meaning wolf, with the addition of a diminutive suffix. The surname originated in the province of Munster in Ireland.

Historically, members of the Uí Duach tribe, who were descendants of a figure named Duach, were prominent bearers of the Nualláin name. This tribe was located in the territory that is now County Tipperary. Over time, the surname spread throughout Ireland and also to other English-speaking countries through emigration. Today, Nualláin is found in Ireland, the United States, the United Kingdom, Canada, and Australia, among other places. While the spelling variations can occur, Nualláin remains the most common form in Ireland.
