ooh my there's a lot to go at there, thank you ! I have checked out the will but i'm sure it's not the James i'm searching for.. he would have been born around 1790, his son Robert was born around 1812-15. So at the time of David's death would have meant James would have been over 60. I have saved a copy of the will, because the Johnston's named, could be related and i may be able to connect them to the family.
I am extremely grateful for all the help i have received so far, in such a short space of time. Can't thank you enough
