Luther

From the experts:

Once restricted to evangelical Protestants honoring the ecclesiastical reformer and theologian Martin Luther, leader of the Protestant revolution. In more recent times it has been favored by parents wishing to honor civil rights hero Martin Luther King Jr. Luther was a Top 100 name at the turn of the last century, but fell off the list in the early 1990s.
Luther Burbank was an eminent botanist and Luther Vandross was a popular R&B artist. It's the name of a main character on the Disney series Zeke and Luther. The name was given a shot of contemporary energy via Idris Elba's dynamic performance in the eponymous BBC crime drama.
