Marin is a lovely county north of San Francisco, and a lovely baby name on the rise, one which sounds more refreshing than the more familiar Marina.
 As a place-name, Marin is pronounced with the accent on the second syllable, Ma-RIN, sort of like Marie, though when used as a name, many would say MAR-in, to rhyme with Karen.
 Marin is unisex in several European countries (in Croatia it's currently Number 29 for boys); Maren is an alternate, Scandinavian, spelling. In France a very fashionable alternative for girls is Marine.

Originally a surname deriving from the Roman twin Romulus, this attractive name was introduced to the English-speaking world as a first name by painter Augustus John who used it for his son. Romilly John became Admiral of the Fleet in England. 
 A French surname from the twelfth century on, it's more recently been heard as a girls' name. Emma Thompson, for example, used Romilly as her daughter Gaia's middle name. And Romilly was used in the US last year for a dozen baby girls.
 The logical nicknames would be Romy or Milly, both very much in style.

Romilly

 Well-used in France, Sidonie ranks in that country's Top 400.
