initial confusion

I'm not sure I want to keep up my web site that lists data about U.S. Senators, including their full names. It's such a nuisance collecting that information on new senators. Take Dick Blumenthal of Connecticut. On just one Google search result page, I've found him listed as Richard D. Blumenthal, Richard M. Blumenthal, Richard S. Blumenthal, Richard T. Blumenthal, Richard J. Blumenthal, and Richard A. Blumenthal. And yes, they're all referring to the right guy.
