Greetings, and a warm welcome to Rootschat.
For the benefit of Rootschatters helping,
FreeREG has the marriage:
George VEITCH to Isbel WINDRUM, 24 Nov 1786, Berwick-Upon-Tweed : Golden Square Scotch Church United Secession Presbyterian, both of the parish, married at Lamerton in Scotland by Jno BLACKHALL, Minr.A quick search for VEITCH in Northumberland didn't turn up anything relevant, so I wonder if either George or Isbel originated from Lamerton (Lamberton, Berwickshire?). The hunt is on!
Philip
ADDED:Children baptised at the Golden Square Scotch Church were:
Janet 9 Oct 1787 (Claribut Mill, Parish of Hutton, Scotland)
Robert b 10 Sep bap 29 Sep 1789 (Clarifemill , Parish of Hutton)
Alison b 20 Apr bap 6 May 1792 (Eastern Lane, Berwick)
Margaret b 20 Mar 1796 (Claribel Mill, Parish of Hutton In Berwickshire, Scotland)
There are two infants baptised in the same church from 1811 to 1818 with parents Robert VEITCH and Alison - who may be related to George.
Genuki
https://www.genuki.org.uk/big/eng/NBL/Berwick/ChurchRecords states that birth registers for Golden Square exist from 1771 - probably too late for George. There are records for Berwick High Meeting Presbyterian from 1761 onwards which may be worth checking.
