Back in the 1980s, working in a very large, university hospital on the edge of a major city ghetto, we had more than a few babies named “Princess” or “Queen.” The general consensus of the staff was- you can say it, but it doesn’t make it so. Then they’d ask us how to spell the second part of the name they’d chosen that none of us had heard before. “Lady, let me do my job and keep your baby alive. Consult your ‘culture’ and get back to me on what you want on the crib card.”
I told a friend of mine who was writing a book about the deep south culture and as an insurance agent in southside of Atlanta, there are MANY named “King” or even “Master” (so their child has to be referred to as “Master” by white people. “Master Smith, the doctor will see you now.” Even had one who named their kid “Doctor.” No lie.
