Ronald "Ron" Witwicky (1960–) is one of six children of Herbert Witwicky and an unnamed female. He has four brothers and one sister; his eldest brother is named Ben. In 1979, the kids split the proceeds from their father's house. Ron named his son an actual real name.
Probably just compensating for his family's history of mental illness.
Ron Witwicky is the head of the neighborhood watch. Considering the fact that five giant robots milled around his backyard and he didn't even know it, he's probably not that good at the job.
He also never went to college, same as every Witwicky before him. So, of course, he has a house nicer than yours, an Austin Healey BJ8, and can afford a trip to Paris while sending his son to Princeton University.
