Lovely to hear from you! I have been corresponding with Lisa Doussard Plegge and between the two of us, we have figured out the connections back to the island of St. Lucia. We don't have a common ancestor, but are connected by marriage. Are you in touch with Lisa?
You information does help and I see your grandfather on the tree that Lisa provided to me. His wife's name was VASHTI WHITSELL, is that correct?
