Hi Army,
Using different spelling for Forrester, found some more family,
George Armstrong, born 30 May 1820, baptised 30 Jun 1820 Edrom, Berwickshire
James Armstrong, born 24 Mar 1818, baptised 19 Apr 1818 Edrom, Berwickshire
Catherine Armstrong, born 18 Apr 1816, baptised 19 May 1816 Edrom, Berwickshire
Found that they were married in Westruther, Berwickshire, on 3rd June 1809.
Could it be that it is Edrom rather than Edinburgh, is the location of the family?
Tom.
