Winny (short for Winifred) Wawa (Yes, this is a real name XD) Whisper Willow Windy Wren Winter Wish (Not sure if it's real, though) Whirl (Again, not sure if it's real) Welcome (A real name, might be useful) Willa
These are only girls names, just so anda know, though a couple of them are unisex I believe. Good luck!
