Show ContentsGillmore 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 or servant of Mary. 1

As an occupational name, the family was known as "the bearer of the broadsword to a Scottish chief." 2 or "follower of the chief, one who carried the chief's broadsword, from gille, a servant, and mor, large, great." 3

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. "The chapel was constructed of wattlework (capetta de virgin), and on its completion Gilmor appointed his kinsman Gillemor to the chaplaincy. These names, it may be mentioned, attest the strong Gaelic influence in Cumberland at that period." 4

Gilmore meaning "Gill the Big" was son of Gillanders the great Chief who lived about 1140.

"Some time before 1144 'Gillemor filius Gilleconel' granted a half mark of silver to the church of S. Machute in Lesmahagow (Kelso, 187). Gillemure Albanach ('the Scot') and Gillemure mac Blancard witnessed the donation of the church of Torpennoth, etc. to Holyrood by Uchtred, Lord of Galloway, between 1153-65." 4

The Gillmore Motto +

The motto was originally a war cry or slogan. Mottoes first began to be shown with arms in the 14th and 15th centuries, but were not in general use until the 17th century. Thus the oldest coats of arms generally do not include a motto. Mottoes seldom form part of the grant of arms: Under most heraldic authorities, a motto is an optional component of the coat of arms, and can be added to or changed at will; many families have chosen not to display a motto.

Motto: Perseveranti dabitur
Motto Translation: It will be given to the persevering.
