I also happen to have many of the names on your list. Such as Henry who is my gg grandfather and an uncle Elmo who my mother says she visited on his deathbed. I have some information on Henry's kids His daughters were -Eileen? who married my g grandfather Cyril? a french mulatto. She is supposed to have a Welsh mother. And I was told her name was Marie, possibly. They are divorced after having children with Eileen immigrating (either her or her daughter, Eula) to Trinidad. -Linda, married Captain Curtis Bradford Wallace, a Scottish sea-captain from a whaling dynasty in Bequia (JBB 1 migrated from France to there). I have a list of some of their kids.
My mother has told me that Joseph Burns I had originated in the South of France and emigrated with his whole family to St. Vincent however only he and his brother survived the trip. They were escaping a war sometime during the middle half of the 19th century.
I realize that you all haven't posted for 10 years almost, but if you are still researching then I would like to receive more information on my (or our) family.
