John Horn birth date in my tree is 19 June 1794. So long ago since I did this branch I'll have to try find note cards which i archived. I'll try and find details.
John married Agnes Pow (Not Ann as some trees state) irregularly 15 February 1791 and is recorded in Church Records as rebuked and married 12 August 1791.
Agnes was daughter of Archibald Pow b 23 February 1738 and Janet or Jannett Pow/Powe b 28 Dec 1742.
Janet Pow/Powe was my Gt-Gt-Gt-Gt Grndmother and Archibald was her second husband. William Anderson was her first.
However, Archibald is also related through blood to me as he was the grandson of my gt-gt-gt-gt-gt-gt-gt grandfather. Small place Cockenzie and Port Seton back then...........
I have Pow line going back to c1610 and Archibald the patriarch of that line.
