Hi Tom I received this reply direct QUOTE: Dear Tricia I am not a member of the forum so not sure if this email will work. Other than its diminutive Lachy you would have to go back to the medieval period where in Scottish Latin documents the name was Latinised as 'Rollandus', modern Roland, but I have never encountered that substitution used in more modern times. In Ireland on the other hand, apart from being 'anglicised' as Loughlin or Laughlin it has also been 'translated' as Laurence. Best wishes. K Tom. In your McQuarrie family do you have Catherine McQuarrie who died 1830 Craignure m Alexander McDougall 9 Jul 1776 Kilninian. Tricia
