Early Origins of the McIlwain family

The surname McIlwain was first found in Dumfries where Thomas Makgilvane was a tenant under Douglas in the barony of Buittle in 1376. The name was derived from the Gaelic Mac Gille Bheathain, meaning 'son of the servant of S. Beathin' (Bean). There are many spelling variations of the name due to the English translation from Gaelic. John Mcilmeyne was a witness in Dumfries in 1477 and Gilbert Makilmeyn de Grummat was listed here in 1503. 1

Allan McYlveine de Grumet who appears as bailie of the Abbey of Crossraguel in 1523 is Alan Makilwene, juror on assize in the bailliary of Carrick in 1532. 1
