Hello, I just saw your reply. I hope it's not too late to contact you.
I didn't make myself clear in my post. When I said Mary and Benjamin were under the age of 14 it was not in 1851 at the time of their grandfather's land partition, but rather at the time of their father David's probate. I did not have the date of that at hand when I wrote the message, but if my memory serves correctly I think that was sometime in the late 1820s. If you'd still like to correspond on this family please contact me.
