Hiya Audry I have exactly the same family tree as you Alexander Gardiner married Elisabeth Gibb on the 5th June 1729 in Falkirk, Stirlingshire they had 10 children 2 of them have the same name Agnes Gardiner one of the Agnes Gardiner's died?? I still have to find a death for her.
I am a descendant of James Gardiner which is Alexander Gardiner's and Elisabeth Gibb's son he was christened on the 15th Oct 1738 in Polmont, Stirlingshire.
I would love and look forward to hearing from soon
Many Thanks
Aaron Gardner
