Pearl is a generally well - meaning mother to Jethro . She was also a popular character , often used as a foil for Granny , and became a regular part - way through the first season ( the end credits were even refilmed to include Pearl with the other family members ) . The character disappeared after the first year because Benaderet had become the star of another Paul Henning series , Petticoat Junction . She is the daughter of Amos Clampett , Jed 's uncle . Like Elly May , Pearl 's name came from that of a character ( Pearl Lester ) in the popular rural - life novel , play , and film Tobacco Road . In the episodes `` The Clampetts Get Psychoanalyzed '' and `` The Psychiatrist Gets Clampetted '' , Herbert Rudley plays the psychiatrist Dr. Eugene Twombley , with whom Pearl is enamored ; Benaderet 's real - life husband was named Eugene Twombly .

Late in the season , it was explained in an episode that Jethrine had returned home to marry Depew , although the wedding was never seen in the series ( nor was Jethrine ever seen again , although she was occasionally referenced ) . Jethro and Jethrine rarely appeared in the same scene in any of the programs , and then they were never on - camera at the same time , except for the rare back - of - the - head shot using a double .

In one episode , Mr. Drysdale forces Dash into courting Elly May by threatening to put him in a television show called Crabman . Elly initially liked Dash and enjoyed being with him on dates ; Jethro , however , was quite enamored with Dash because of his playboy persona . Riprock was a send - up of the blatantly fake screen names employed by a number of movie actors of the period . Riprock 's real name ( before being changed by Hollywood moguls ) was `` Homer Noodleman '' , and he was from Peoria , Illinois . </Li> <Li> Lowell Redlings Farquhar ( played by Charles Ruggles ; three episodes in seasons 4 and 5 ) is the elderly father of Mrs. Drysdale .
