What was the name given to Superman by his adoptive parents?

In most versions of Superman's origin story, Jonathan and Martha were the first to come across the rocket that brought the infant Kal-El to Earth, with their adopting him shortly thereafter, renaming him Clark Kent - "Clark" being Martha's maiden name. They live in the small town of Smallville, Kansas. The couple is usually portrayed as either late middle age or elderly.
