Real family name is Yurosek. From a family of carrot growers started in
California by Samantha's grandfather John Yurosek. Her father actor
Gary Lockwood changed his name from John Gary Yurosek for the screen. He took
on the last name Lockwood after he got his first job as an actor by
director
Joshua Logan Lockwood. Gary thought no one would be able to
pronounce his birth name when listed in the credits, that's why the
name was changed. Samantha is now coincidentally dear friends with
Joshua Logan Lockwood's descendant
Billy Lockwood, also an actor, and currently
filming
Wild Hogs (2007) starring
John Travolta.
