I don't have any family in the industry but there are a few celebs who come from my hometown, and two of them both have Bacon Numbers of 2.
David Huddleston was in Santa Claus:The Movie
with John Lithgow, who was, of course, in the original Footloose
with Kevin Bacon.
Wayne Newton was in Best of the Best 2
with Chris Penn, who was also in the cast of the 1983 Footloose.
