I don't know about regiments in Berwickshire apart from the Berwickshire Militia, but I have come across mention of some regiments about 1813 in the town of Berwick. They are the 2nd Battalion of the 25th Regiment of Foot (later the King's Own Borderers): the 1st Battalion of Royal Scots ( the Lothian Regiment) and the 4th Battalion of Royals. Members of these regiments all had children baptised in the town of Berwick about 1812 to 1815.
Hello Myra Thanks for the info. I am actually trying to trace the parents of this elusive James Reid, I don't really know where he was actually born whether it be Ayrshire or Renfrewshire.
I went up to Edinburgh the weekend to NRH but that is the only info I got was that he was a soldier in Berwickshire.(frustrated or what)
