Fascinating how familiarity with one famous person can make a name seem normal instead of "bizarre."
Gower seems perfectly normal to me (if rare) because I am old enough to be familiar with the choreographer Gower Champion, who was one of the best known Broadway performers during his lifetime. I was surprised to see when I looked him up that he's been dead since 1980.
He pronounced Gower to rhyme with "power" or "flower", by the way.
