It reminds me of a girl I went to school with named
Theodore. Her parents named her
Theodore because she was the fourth girl, and they had wanted a boy. She went exclusively by
Thea. Technically any name can be unisex, but no one else is going to see
Vincent and think girl.
Heck, when I make appointments or interviews under the name
Sam (which is unisex), the first comment I always get is "Oh, I thought you were a man." One can argue this shouldn't matter, but a child would still have to deal with this constantly. Additionally,
Vincent does not have any feminine-sounding nicknames, so she wouldn't have anything to fall back on should this bother her.
