I don't like it

...but, to me, word names aren't automatically unisex just because they're words. I actually get a distinctly feminine vibe off Wren, both because of the daintiness of the little songbird and my associations--the littlest daughter from the comic Baby Blues and the only IRL Wren I know, a 10-month-old girl. I really like Wren for a girl, perhaps as a mn.
If I wanted this sound for a boy, I think I'd opt for Ren.
