There is: 1 person with my name in the U.S.A. How many have your name?

I know that there's a Marine Engineering Mechanic in the Royal Navy by that name, and a Cub Scout leader in Wales. (It's possible, I suppose, that they are both the same person. But there's at least one other "Ian Osmond" in the world, and probably at least two. Just not in the USA.)
