8. Dylan
Dylan, which means "son of the sea," is a popular name choice. It's derived from Welsh folklore, after a legendary seagod whose death caused British and Irish waters to "weep." It's also the name of the late, great Welsh poet Dylan Thomas, of "Do not go gentle into that good night!" fame. Your son will have quite a few namesakes to look up to. Plus, the name rolls off the tongue, doesn't it?
