Gillmore History, Family Crest & Coats of Arms

A Strathclyde-Briton family from the Scottish/English Borderlands was the first to use the surname Gillmore. It is a name for a devotee of the Virgin Mary. Looking back further, we find the name Gillmore was originally derived from the Gaelic Gille Moire, which means follower of Mary.

Early Origins of the Gillmore family

The surname Gillmore was first found in Ayrshire (Gaelic: Siorrachd Inbhir Àir), formerly a county in the southwestern Strathclyde region of Scotland, that today makes up the Council Areas of South, East, and North Ayrshire, where they held a family seat from very ancient times. Early records from Cumberland show that between 1133 and 1156, Gilmor, son of Gilander founded the chapelry of Treverman (later Trierman) in the parish of Walton, Cumberland, site of Triermain castle. Gilmore meaning "Gill the Big" was son of Gillanders the great Chief who lived about 1140.
