Are Zoe and Emily Deschanel related to Chris Deschanel a director on Twin Peaks?

Answer 1

You probably mean Caleb Deschanel, who directed 3 episodes of the show, and yes, he is the father of Emily and Zooey. As a matter of fact, their mother, actress Mary Jo Deschanel, was also involved with the show, playing Donna Hayward's wheelchair-bound mother.
