Kathleen Bowman, who is the mother of Grace Bowman, adoptive mother of Tom Bowman, the ex-wife of George Juergens and newlywed of Jeff Tseguay. She cheated on George during their marriage. As a teen, Kathleen's mother did not let her have any physical contact with any boys. She told Grace that she only married George for sex. She waited until she married Marshall to have sex with him. She becomes a widow after Marshall dies in a private jet crash and began dating a guy named Dr. Jeff Tseguay, a gynecologist, much to Grace's displeasure. Kathleen and Jeff are so excited that Grace suddenly seems to be in favor of the marriage that they impulsively decide to marry right away. Kathleen therefore changed her name from "Bowman" to "Tseguay".
