But you'd be Antonina to my grandmother.
My parents named my oldest sister Svetlana, which is the name of the pagan goddess of light, so she had to be baptized Photinia because she was born a few days away from St. Photinia's feast day. They chose that rather than Thecla, the saint on whose day Lana was born.
I'm not finding a Saint Kelly, by the way. There's a St. Celsus that the Irish claim, but he's so minor that the Russian Orthodox church doesn't even recognize him.
