Just like Stacy, Ashley and Kelly, lots of names start out as men's names and become unisex. I understand in Europe it would be understood that Marin is a man's name, but that doesn't mean it is WRONG to be a female name too. I plan to use Marin or Maren for a daughter.

Marin could be an alternative form of Marina as a girl's name. Regardless if it's used or understood as a boy's name in other parts of the world, there are many other examples of "name switching" as well as unisex names throughout history. You have to understand that language and culture change. Descriptively speaking, if a mass amount of girls have this name (in the US), then it IS a girl's name until usage proves otherwise.

Rare in france. Maybe cause it's noun for mariner.

This is one of the most popular names FOR BOYS in Croatia. I have 3 boys in my class whose name is Marin.

My last name is Marin. I never thought it was a first name. My last name comes from Spain way back in the days when Spain invaded the Aztec and fooled them. Oh well, that's another story.

Males named Marin are also found in Croatia. This could be because of the Venetian influence on the coast. Although, there are many male inhabitants of the city of Dubrovnik with the name which suggests a different influence. Marin Drzic, a writer from Dubrovnik alive in the 1500s (who happens to be the person I was named after), is probably the most famous. [noted -ed]
