Gillmoor is English in Origin.

Gillmoor combines English topographic elements with Gaelic surname heritage. One reading treats it as a place‑derived name: Old Norse gil (“ravine, gully”) plus Old English mōr (“moor, heath”), yielding “moor by the ravine.” Alternatively, it aligns with Gilmore/Gilmour, Anglicisations of Gaelic Mac Gille Mhoire, “son of the servant of Mary.” The double‑L spelling echoes English “gill” while preserving the Gilmore sound.

Within the wider Gilmore/Gilmour surname family, attested since medieval Scotland and Ireland, Gillmoor as a given name is a recent, rare choice in English‑speaking countries, shaped by the modern surname‑as‑first‑name trend. Awareness of the base form rose via Gilmore Girls, though this spelling remains uncommon. Variants include Gilmore, Gillmore, Gilmour, Gilmor, Gilmoor; short forms Gil and Mo/Moor. Overall sense: “moor by the ravine” or “devotee of Mary.”
