I don't know if you're from the U.S. or the U.K., but I know in the U.K. "-wich" and "-wick" names have silent Ws, whereas they're often pronounced in the States. (This is why Warwick is usually spelled Warrick as a personal name in the States, even though it still isn't a common name.)
I bring this up because I think Renwick sounds far more attractive with the British pronunciation (REN-ik) than the American one (REN-wik). How did he say it?
