My given name was plenty unique enough for me to risk the chance being confused with all the other Severns in here, so I choose to use it. That said, I will always have to continually let people know in a printed word situation that, YES, I AM male and NO I WASN'T named after either of the rivers (being a lifelong Marylander who chats with Brits online, it comes up a lot), but rather, named after my Great Grandfather.
