Bryony is an unusually strong plant name --the bryony is a wild climbing vine with green flowers --that caught on in the U.K. before sprouting here. The name of the young character in the Ian McEwan novel Atonement is spelled Briony, which is the variation and Bryony the original.

Popular in Wales, familiar across the UK, and ultimately derived from the Germanic Adalheidis, this isn't a creative respelling of a classic, but the Welsh variant of it.

Very popular in Wales, this perfectly nice name's only problem is its similarity to the dated Beth Ann. But if you're looking to honor an ancestral Elizabeth with a distinctive rare choice, Bethan might be on your short list.
