Hi Barbara
Thank you - the information you have listed basically matches with what I have figured out, but was hoping for a baptism for proper "proof"....alas, seems not to be the case !! Its like a detective story isn't it !!! I think that Thomas and Agnes Johnson possibly had 7 children in total with Nichol who married Elspeth Tait as the eldest.
Thanks also for the stone in Greenlaw, whilst I had the burial inscription for James and Alison, I didn't have the bit about Nicol or Janet !!!
Cheers
Victoria
