Briony

I quite like this name but prefer Bryony.
Sister Briony was one of the nuns in the movie "Black Narcissus" starring Deborah Kerr as Sister Clodagh, based on the novel by Rumer Godden. In the movie Briony is pronounced like Brian with a y at the end. I had hoped it would be pronounced with a stressed OH sound in the middle, but at least I found out how to pronounce it.

Briony is the main character in the novel Atonement, by Ian McEwan.
