In the interests of historical accuracy can I point out that we never had Squires in Scotland. [chorus of song]
The equivelent to the English Squire was Laird and even Dukes when they were on their own lands were referred to as The Laird.
Sorry to be so pendantic but as this is a worldwide forum it is as well to keep the record straight.
Sir Walter Scott has a lot to answer for as he introduced English terms which were not used here before his time, a good example being "Hamlet" in place of "Clachan". Sir Walter was brought up in the only part of Scotland where gaelic was never in use if we can judge from the scarcity of gaelic place names in the extreme South East of the country.
