If there isn't a particular name which has a special meaning for you, pick whatever you like! Be creative - why not, Daniel Shakespeare? why not Daniel Thelonious? You should choose a name you either love the sound of or that has a special meaning for you!
Daniel Algernon, Daniel Valentine, Daniel Auberon, Daniel Frederick, Daniel Willoughby, Daniel Barnabas, Daniel Chester, Daniel Joseph, Daniel Francis, Daniel James, Daniel Sebastian, Daniel Oliver, Daniel Theodore, Daniel Rowan, Daniel Gregory, Daniel Emmett, Daniel Justice, Daniel Noble, Daniel Phineas, Daniel Heathcliff, Daniel Tristram, Daniel Garnet, Daniel Bravery - just about anything goes. With such a solid, sensible first name, I think you can afford to be a bit more outlandish with his middle name. Just don't pick something that would lend itself to too much ridicule...
Let us know what you pick!
