Hi, I am also researching a Marigot family of Morales. I went to St. Martin in 1978 and me a Mr. Vere (I think that was his name) Richardson who lived in Marigot. He had a son who was an artist (quite accomplished) He told me that his mother and my ex-husbands mother "name of "Flanders" were sisters. Since it is such a long time ago I am not sure I have the details correct. I remember going into his house above a store and seeing the pictures of the sisters as well as the paintings of his son who I think was named
Roland Richardson. I also attended an art show in NYC for his work. I see he has a website in St. Martin. I hope this helps. If you come across anything on the family of Georges Morales I would appreciate hearing about it.
