S01E25: The Family Tree

Mrs. Drysdale wants to get rid of the Clampett's before the arrival of Mrs. Smith-Standish, the head of a 'first family' historical society. But Smith-Standish goes to the Clampett's first and becomes enchanted with their antiques and way of life. She also finds evidence that Jed's ancestors came to America prior to the arrival of the Mayflower. She ropes Mrs. Drysdale's into helping with chores done the old way, to Mrs. Drysdale's horror.
