Actually, come to think of it, that's less of an amazing coincidence and more of a statistical likelihood; pulling from approximately the same-sized population pool, there have been an identical number of Moores and Taylors to make the big leagues so far. (There has never been a player named "Taylor Moore," though.)
Obviously, that Taylor total does not include the four men who bore that appellation as a first/given name, nor the dozen who had it as a middle name. None of those 15 were All-Stars, either, with 2B Elliott Taylor "Bump" Wills the biggest name and 1920s-era OF Taylor Douthit probably the best player.
As with the Moores, no Taylor has yet been inducted to the Hall of Fame; but where the Moores had five former All-Stars available for roster selection, the Taylors have managed just one, former PHI 2B Tony Taylor. One place the Taylors have the advantage on the Moores ...
