Or maybe just 'Lou'?

'One man who has struggled more than most with his moniker is Lucifer Howse, a 33-year-old alternative medicine practitioner in Brighton. Mr Howse only discovered his true first name in his late teens - prior to that, his family called him Luke for short. "I had a real crisis when I found out my name was Lucifer. I went off the rails", he says. When he picked up his driving licence a few years ago, the woman behind the counter barked Biblical phrases at him and shouted: "It's you. I know it's you." But he has now embraced his name. "People don't automatically call their children William, Henry or Mary anymore. They are more experimental."'
