For a boy or girl?
I prefer
Marian on a girl and
Marion on a boy, though I like
Marian on a boy too just because I like the way it looks better. In general I like the name itself much better for a boy too. It's very handsome and gently friendly. Swoon.
Favorite combos:
Marion AbrahamMarion BedeMarion ConorMarion Hartwick
Marion Rory
Not sure how I'd pair it for a girl, maybe like
Marian AlexandraMarian CatherineMarian EugeniaMarian GrainneMarian Swanhild - oohhhhh
