Dear Julie,
A little late a reply to your post of 10 years ago, there are three root families who call themselves Squair.
1. My Line,
Burgess of Stirling and Edinburgh, London Graves End area Australia, Western Canada and the rest of the world are connected to the ancient source in Perth; Squire and Knight of the temple. They were called to Stirling in Medieval times to be bailiff of Stirling Castle and were out in 1745 with the Perth Horse Cluny McPherson Clan Chatten.
2.
Nairn Scotland this family is descended from one Alexander Squair hired by The Brodie to run his estate. The Brodie saw fit to change Alexander’s name to Squair so they have no ancient connections to Squair of antiquity. Locations Nairn, Glasgow, London, Eastern USA and Canada.
3.
Edinburgh Squair were butchers and later surgeons and prominent in the local government of Edinburgh they are believed to be connected to the ancient source in Perth Squire and Night of the temple.
For more on the ancient Squair family see Black published in NY.

William
