Tully

The name Tully has a dual origin. As an Irish surname, it is an anglicized form of several Gaelic surnames, primarily Ó Taithligh, meaning 'descendant of Taithleach'. Taithleach itself is derived from 'taithleach', meaning 'peaceful' or 'quiet'. Another Irish origin is from Mac an Tuile, meaning 'son of the flood'. As a given name, it can also be a diminutive of the Roman family name Tullius, which is of uncertain Etruscan origin, possibly meaning 'hill' or 'boundary'. Its use as a given name in English-speaking countries is relatively modern and often influenced by its surname origins.

In contemporary usage, Tully is more often encountered as a surname, but its charm and simplicity have led to its adoption as a given name for both boys and girls. The diverse etymological roots contribute to its versatile appeal, offering meanings ranging from tranquility to natural forces. Its unisex appeal has grown, particularly in Australia, where it has seen some popularity.
