From the experts:
Maren is one of the many twenty-first-century takes on Mary--but we find the more classic Marin spelling preferable. When spelled Maren, the pronunciation seems more clearly to resemble Mary, with the emphasis on the first syllable. Marin, the spelling also used for the beautiful coastal county north of San Francisco, is often pronounced with the emphasis on the second syllable, as in Marie.
