McTaggart

McTaggart is a Scottish surname, primarily a variant of Taggart. Both names are Anglicized forms of the Gaelic Mac an tSagairt, meaning "son of the priest." This origin dates back to a time when clerical celibacy was not strictly enforced in the Celtic Church, allowing priests to marry and have children. The surname thus began as a patronymic identifier for the offspring of clergymen.

Etymology and History

The Gaelic root Mac an tSagairt combines mac ("son") with sagart ("priest"), a word derived from Latin sacerdos. The emergence of this surname reflects medieval Scottish and Irish society, where priestly marriage was common until the widespread adoption of Roman liturgical reforms. The name was originally borne by families who served local churches or monastic communities. Over time, the Gaelic form gave way to Anglicized versions such as Taggart, MacTaggart, and ultimately McTaggart.

Variants and Language Forms

The surname appears in multiple linguistic traditions. In Scottish usage, Taggart and the original Mac an tSagairt are prominent variants. In Irish contexts, the same Gaelic form is found , often Anglicized as Taggart as well. The prefix Mc-in McTaggart represents a common Scottish contraction of Mac, while Taggart drops the prefix entirely.
