A perfect spin-off from Perfect Strangers. Family Matters focused on Harriet Winslow (the elevator operator from the Chronicle) and her family of sorts. Carl Winslow, her husband, was a dutiful cop, and a gruff and lovable father
    to three kids: Eddie Winslow, the rebel son; Laura Winslow, the smart-alec daughter; and cute little Judy Winslow. They had opened their home to Harriet's sister, Rachel
    Crawford and her little baby son Richie, and in the very first episode, Carl had to open his home to his cool and streetwise mother, Estelle Winslow, whether he wanted to or not. Everything was going along just fine until one day, Steve Urkel, the inventive nerd, barged into their home and eventually, into their hearts. Steve had a
    killer crush on Laura, but she would never give him the time of day. Steve Urkel was intended to be a one-shot appearance, but his popularity with the fans won him the number-one spot as America's favorite nerd.

    Following season four Jamie Foxworth who portrayed Judy Winslow was fired and her character was written off the series with very little or no explanation as to why.

    She would finally be replaced three years later by an runaway orphan named 3J played by Orlando brown. He was a streetwise kid just looking for a real family the Winslow's took him in and he and Richie became best friends.
