I really dislike it. Its got that old-man feel to it, and I really dislike
Harry. I would only suggest a more popular/trendy/classic name as a mn if you did use it to bring it into modern usage.
My bias comes from having a friend (
Walter Harold) who was named after his grandfathers, but every time he meantions his name, everyone tells him he has an old man's name (he's 23).
