Comments for the name Alexius

As crazy as it may seem, I thought this name was a girl's name. I'm a writer, and while trying to think of an interesting name for my female lead character, I thought "Alexis" or "Alexus". Then I thought, "why not make it interesting and combine the two to make it 'Alexius'?". I pronounced it "uh-lex-ee-us", though I'm not sure what the technical pronunciation is.
