I have personally encountered "Null" as a surname in system used by job applicants world-wide. The system's session layer encodes absent values as the string "null" at some point. The Null clan is the only problematic case, and they are numerous enough that the maintainers are aware of the problem but not so numerous to fix the session layer.
I wish I could listen in on a dinner conversation at Null house. They must have an interesting perspective about computers.
