Just for clarification, do you mean the UEL Elizabeth (1770-1866) and Farrington Ferguson (1765-1842)? She was my third cousin 5X's removed.
In Ancestry, this is where many people's tree are incorrect in that they would have Elizabeth as my ggggggrandmother.
If I could have you e-mail address, I will give you access to my tree as well as a copy of a booklet that I have recently written which I presented at last year's Cole Picnic in Codrington -- I think that it was their 126th consecutive picnic.
I would love to know more about the stories passed down by you family.
