The 2004 Pixar movie The Incredibles follows the lives of the forcibly retired superhero Mr Incredible and his family. Shortly after we are introduced to Robert (Bob) Parr we discover that he and his family are in some sort of witness relocation program to hide their former identities from the public allowing them to lead normal lives. We also know that this isn't the first time they've had to move as a result of Bob's actions.
Presumably each time the family is forced to relocate they must also change their names as otherwise tracing their identities would be trivial. As such my question is this:
What was Mr Incredible's real name before he first went into hiding?
