Stella Mudd's mother was the otherwise unnamed mother of Stella Mudd and was married to Baron Grimes.
History and specifics[]
In the 2260s, Stella's mother lived with her daughter in the residence Stella once shared with her husband Harry Mudd on Stella Mudd's planet.
In 2270, Harry was brought back to the residence by James T. Kirk, Leonard McCoy and Yeoman Weinberg. They were greeted with insults by both Stella and her mother, who then fired a shotgun filled with pellets at Mudd's feet. She whispered into Stella's ear, suggesting that she flirt with McCoy, then aimed a shotgun into McCoy's ear. Weinberg quickly stunned both women with his phaser, and the landing party quickly departed. (TOS - Mudd's Angels short story: "The Business, As Usual, During Altercations")
