Hi Andrea, I hope you're doing well...it's been a while. I am in touch with someone who is exploring areas that you mentioned in your 2015 post.
There is a gentleman in England who contacted me recently. He is researching Montserrat descendants... tracing them back to their slave ancestors on the island in the late 1700s and early 1800s before Emancipation. He is looking for descendants in Montserrat and around the globe. His name is Alan Taylor and his email is email@example.com
You mentioned that your grandmother is the author of the "family list" that most of us Boatswain cousins use to jump start our research, I think that he would love hearing from you. He's been tracing Patrick and Sita's descendants.
