Hmmm,if they are related Jean I don't think they are direct line.They were still further east at this time in Currie,Ratho and Kirknewton.The first names don't feature much either,it's usually George,John or Peter followed by Alexander and Thomas.And in the females Elizabeth,Margaret and Agnes followed by Janet and Christian.I have them back to 1715 at the moment and no James or Isabella that I can see.Thanks for looking.
George.
