Gillmor is in Origin.

Gillmor is a surname-turned-given name rooted in Gaelic tradition. It derives from Scottish Gaelic Gille Mhoire and Irish Giolla Mhuire, literally “servant/devotee of (the Virgin) Mary.” In medieval records the patronymic Mac Gille Mhoire/Mac Giolla Mhuire appears across the Scottish Lowlands and Ulster; later Anglicization yielded Gilmour, Gilmore, Gillmor, and Gillmore. Some etymologies also cite gille mòr “great servant,” but the Marian reading is standard.

As a first name, Gillmor fits the English-speaking habit of promoting surnames to given names, recorded sporadically since the 19th century and revived in modern times. It reads tailored and traditional, typically masculine yet workable as unisex. Variants and related forms include Gilmore, Gilmour, and Gillmore; the Gaelic originals Giolla Mhuire/Gille Mhoire persist in Irish and Scottish usage, often as elements in devotional names. The core meaning evokes loyal service and reverence, with a quiet nod to Celtic heritage.
