Bonanza S10 E08 Little Girl Lost

"America's Favorite TV Western"

A bratty 10-year-old girl named Samantha, whose mother is Ben's cousin and is a third cousin of Hoss and Little Joe, comes to the Ponderosa. While she proves to be a handful, Ben (who tracks down the girl's mother) really has his hands full when her grandfather comes to the Ponderosa demanding custody.
