As for the two soldiers John and John in the 1825 military listing possibly being JFB's and JSS's fathers, and the dates on the military list being their enlistment dates, does that math work out?
If they are enlisting in 1803, about how old are they at that time? Let's say 18.
Jessie was born in 1828, 25 years later, so in this scenario that would make soldier Sutherland about 43 at her birth.
JFB was born in 1829, 26 years after John Burke's enlistment, so at that time soldier Burke would be about 44.
So I guess it's certainly possible that these two gents are the dad's of James and Jessie.
Am I getting this right? I guess the soldier's age at enlistment is very critical to this conjecturing.
Or not... Males can father children way late in age.
