Hi Cheryl
The Samuel McNairn I mentioned would also be my 4 x great grandfathers brother! The Brother I'm related to is Alexander born 1739 married Agnes McKie, their son William born 1780 married Mary Thomson, their son Samuel born 1830 married Isabella Wallace married Mary McNairn married Janet/Jean McNairn!! (lively character) the last wifes daughter is my grandmother.
I hope I haven't confused you, I certainly have myself. Good to hear finally from someone who is connected all be it somewhat tenuously (probably) Who are you related to down this big long line?
Regards
Alison
