Marquise

While I know that male babies are sometimes named "Marquise," this always gives me pause because, in European hereditary, a Marquise is a noblewoman. Her husband is a Marquis. For example, the French aristocrat and military officer who was a general in the American Revolution and a close friend of George Washington's full name was Marie-Joseph Paul Yves Roch Gilbert du Motier de Lafayette and his title was the Marquis de Lafayette. His wife Marie Adrienne Françoise de Noailles was the Marquise de Lafayette. Thus, naming a baby boy "Marquise" seems very similar to calling him Duchess, Countess, or Princess.
