I am now researching this line & may be able to provide some further detail on Andrews Children. I see you have the children of his son James, I also have his son John marrying Agnes Davie, with 6 children.
I am unable to Link Andrew to John & Helen Smart. you list them as his parents, I can see a birth for an Andrew in Kirriemuir to a John but also a 2nd Andrew born in 1726 to a James Wilson. I was wondering if I am missing something? do you have a further source to link Andrew to them?
