I've put a lot of time and quite a bit of money in on working on my Scots. Sometimes, I have to keep going back to maps to see where the parish and towns are located. That's why this takes so long.
Notice that Helen Bell's parents must have already been related. It says very clearly that her maiden surname was also BELL.
The name Jane or Jean predominates in later generations of this family. I think my family must have known some genealogy or they wouldn't have kept doing this. I was surprised to learn that the old lady I knew as "Great Aunt Jeannie" was really Jane Smith Broadfoot.
