Think you know all there is to know about the stars? 

You may be surprised to learn just how many of your favorite celebrities had relatives in the business before them.

Bet you didn't know:

• Garth Brooks' mom was a successful country singer.

• Jon Voight's brother wrote 60s hits "Wild Thing" and "Angel of the Morning."

• Rosanne Arquette's uncle was Hollywood Squares regular Charlie Weaver.

• Hobbit Sean Austin is the son of 1960s TV icon Patty Duke.

Far be it from us to suggest that these folks didn't get where they are by their own talents and abilities. 

We'll let you be the judge!
