The name Swan is a girl's name of English origin. Swan and is often added to user-created lists like Bird Names and discussed in our forums with posts like "Harry Potter House Sorting Name Game".
From the experts:
Obsolete Swanhild gives way to oh-so-modern Swan, joining the flock of newly fashionable bird names such as Wren and Lark. And Swan carries an image of grace, though perhaps also a bit of languor. No matter: It's a lovely and original name, right for our times.
