Seriously, I hate to write this, but the patch of land in the Caribbean is called "Saint Martin" in English, "Saint-Martin" in French and "Sint Maarten" in Dutch, Yes that whole Island has different names in different languages, whodathunk.
That island is divided in two, with a Dutch-speaking autonomous state* that is a member of the Kingdom of The Netherlands and French-speaking part which belongs to France.
To quote the Dutch wikipedia:
Sint Maarten (Frans: Saint-Martin, Engels: Saint Martin) is een eiland in de Caraïbische Zee (emphasis mine)
* I use terminology as on the French wikipedia page, you can try and amend the article if you so wish
