Now this strongly reminds me of the joke/riddle where Emily says: "We are five girls at home: Lana, Lena, Lina, Luna and …? "
My friend’s name is so common her parents double-barreled it so she wouldn’t have to share her whole name at least (which worked out!) and her brother is named Bernhard. Total Old Man Name and not even a common one. They have another sister who’s name is somewhere in between.
