Telltale initials

It has fallen out of vogue in the last couple of generations, but at least until the generation before mine, it was common to see men named after some famous person, e.g., a President of the United States. Thus, if a man's initials were G. W., it was at least likely that his given name was George Washington, and if T. J., he was Thomas Jefferson, and if A. J. he was Andrew Jackson. The times do change.
