Gilchrist
A Gaelic surname meaning “servant of Christ,” originally formed as a devotional personal name or byname.
The #2,811 most common surname in the United States (2010 Census) — about 1 in every 24,074 Americans shares it.
Etymology
Gilchrist comes from Gaelic elements meaning “servant” or “devotee” plus “Christ.” The form appears in Irish and Scottish Gaelic as Giolla Chriosd / Mac Giolla Chriosd, literally “servant of Christ” or “son of the servant of Christ.” Over time, these devotional Gaelic names were inherited as surnames, producing forms such as Gilchrist, Gilcrist, and Kilchrist.
History
19th- and early-20th-century surname writers treated Gilchrist as a classic Celtic religious name, especially in Gaelic-speaking parts of Scotland and Ireland. The name also appears in Manx and Scots-related forms, and several variant spellings are recorded in older sources. It was often explained alongside related surnames built from the Gaelic giolla/gille element, meaning servant or follower.
