The 60s were an era of inclusivity, although I don't recall that the term had been coined yet. The Polaris ballistic missile submarines had "Famous Americans" names, a category which eventually included Hawaiian king Kamehameha, South American liberator Simon Bolivar, and Indian chief Tecumseh - AFAIK the only American military ship name to commemorate someone killed by the American military.
There have been two USS Semmes and three Buchanans, the first of each in the massive WWI destroyer program. The last pair were in the 1960s Charles F. Adams class of destroyers, which also included Waddell and Tatnall.
