Kim's birth name is Kimberleigh Marie.
According the Kroy Biermann's wikipedia page, "Kroy's parents and immediate family all have names that start with the letter 'K.' Wanting to keep the tradition going, Kroy's mom didn't like the standard names that started with 'K, 'so she looked in the phonebook, found a last name that started with 'K' that she liked, and went with that."
