Judith "Judy" Winslow (born 1979) age 36 is one of the supporting protagonists of Family Matters.
It is suggested that Judy had a strong relationship with her older sister, Laura. Though sometimes, she's much closer to Eddie due to his laid back, rebellious nature when he was younger.
When the show began, Judy was 9 years old. During her years on the show, Judy attends an unnamed elementary school, and also an unnamed junior high school.
In the series' fourth season, her character later disappeared at the age of 13, with no explanation as to why. As the show started revolving more around the character Urkel, the producers of the show thought that Judy was unneeded, and she was more of a background character who was given very few lines. After she disappeared in the episode "Mama's Wedding", the cast of the show acted as if she never existed and Harriette and Carl acted as if they only had two kids- Eddie and Laura. Judy was last seen as the flower girl in that episode. In the rest of the series, it is conceivable that she was somewhere else at that time.
William Bickley, the show's creator and a writer of the show, said that she was cut due to a "budget consideration".
If the show continued on into its final season, Judy would've attended Steve and Laura's wedding and revealed she had been living with her aunt, Rachel, in Detroit. Had the show not been canceled Rachel and Judy would have returned home for Steve and Laura's wedding. It's unknown if Rachel, Richie, Estelle, and 3J would have been at the wedding.
