I’ve always assumed Linton Kwesi Johnson was named for LBJ (or at least was a stage name that was a play on LBJ’s name) but googling shows no evidence for the that.
There’s also this:
There was apparently a trend in the Dominican Republic (and perhaps other nearby countries) for a while, during which boys were given the names of American presidents and other historical figures. My barber is names Franklin, and he’s got friends and cousins with names such as Jefferson, Washington and Roosevelt.
And slightly off-topic, but there is a baseball player from Costa Rica whose name is Yeltsin Tejeda - named after the Russian Premier.
Mr. Truman was far from a hermit. He owned a lodge and campground on Spirit Lake. My wife and her parents were regular visitors at the lodge and have pictures of themselves taken with Harry.
Sorry, I didn’t mean any offence. I remember hearing that Mr. Truman was warned about the approaching blast, but chose to remain at his residence. The media portrayed him as an old man set in his ways, too stubborn for his own good. Of course, he may not have been like that at all.
Roosevelt Franklin attended - or worked at - ROO-SE-VELT FRANK-LIN (baaaaaaah) E-LE-MEN-TA-RY SCHOOOL. What are the odds?
Oddly enough, there really was a Benjamin Franklin Pierce. Sanders Theater at Harvard University is part of a Memorial Hall, and one of the names carved into the wall (in what is the waiting area for the theater) is Benjamin Franklin Pierce.
Hiester Richard Hornberger*, who wrote the novel MAS*H under the pseudonym “Richard Hooker”, wasn’t connected with Harvard in any way, and doesn’t seem to have spent any time there. It’s possible that he saw the inscription, or it might just be a coincidence.

Corroboration – The Philosopher's Stone: TRIOS
By the way, since I’ve already commented on one fictional person here, I’d like to note that Robert Heinlein had a soft spot in his heart for people incorporating presidential names into those of their kids. More than one Heinlein hero has such a name.
(Andrew Jackson Libby, Woodrow Wilson Smith, etc.)
Uruguay’s football national team manager George Washington Tabarez.
(if you ask around here (Argentina) we would tell you than half the male uruguayan population has names like “Franklin” or “Washington”, wereas 3/4 of the Paraguayan male population is called “Nelson”, I wonder what names they sterotype us with? “Juan Carlos” or something like that probably)
Alexander was mostly addressed as “Pete” during his playing career.
James Garfield Davis, grandfather of Jim Davis (creator of Garfield).
I once worked with a John Fitzgerald Kennedy. Born several years after the president’s death, his parents gave him that name because they admired the late president. He told me that a few times when the police stopped him and asked his name they would not believe him until he showed his ID.
Then there is also this John F. Kennedy who received the death penalty for participating in a really terrible murder:

His name is Oscar Tabarez, but his middle name is Washington. And he’s got a big game coming up in about an hour.
My great grandfather was James Monroe Hightower, born in 1879.
True that, I was going by memory and it failed me.
But we won the big game anyway 
My great great grandfather was George Washington Lastname
