Hi Perry, It's good to meet you. I know of Henry Boatswain primarily through records or through some of his other grandchildren on Ancestry or on Facebook. Join us in the FB group Boatswain Connection; there are lots more cousins to meet.
I am aware of eight of Henry and Nora's children. I don't have any record of an Aruba family. Do you have specific details?
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 firstname.lastname@example.org
