Hey,

I am wondering about the James Vaters and Elizabeth Hackett you mentioned. I believe they had Winter Houses in English Harbour East, and my great great grandfather Michael Hynes had a sister named Ellen Hynes, who was married to a John Vaters who I think may have been your John Samuel Vaters.
Also a John Hynes married a Mary Ann Vaters in English Harbour East of the same era. Thanks devongriffin1
