<P> Jenny Willis - Jefferson (portrayed by Berlinda Tolbert, except for her first appearance in All in the Family, when she was portrayed by Lynne Moody) is the only daughter of Helen and Tom Willis, the younger of their two children . Jenny is an intelligent person, finishing college with her boyfriend, Lionel Jefferson . At first, George often disapproved of Jenny loving Lionel merely because she is, in George's own word, a "zebra". George calls her this because her mother is black, but her father is white, thereby making her biracial . However, after George discovered Jenny was pregnant with his grandchild, he changed his ways and became much more accepting of her . In 1976, Jenny marries Lionel, though they divorced in 1985 after nine years of marriage . She and Lionel have a daughter named Jessica (played by Erin Hollin and Leslie Hollin (Seasons 6--7) and later by Ebonie Smith (Seasons 10--11). </P> <P> At first, Jenny disliked her brother Allan when he came home after two years in Paris, mainly because she turned out "black" and he turned out "white". But as siblings go, they reconcile and return their love for each other . Their love stayed strong, as Jenny asked Allan to be Jessica's godfather . But since Allan was snowed in, Harry Bentley was to be the proxy . </P> <P> Allan Willis (Andrew Harold Rubin / Jay Hammer) is the Willis' only son and older brother of Jenny . Andrew Rubin appears as this character in the first season finale episode entitled "Jenny's Low" (aired on April 12, 1975), in which Allan returns from Europe, and is given the "Cold Shoulder" by his sister, Jenny (Berlinda Tolbert). Jenny starts staying at the Jeffersons' apartment as long as Allan stayed at their own home . She was somewhat jealous of Allan turning out to be "white". They eventually reconcile . In the 1978--79 season, which is the fifth season, Allan is now portrayed by Jay Hammer, who joins the cast in a two - part episode of the season opener . Allan returns from New Mexico, while his parents return from Syracuse after Tom's father dies . Allan is left the Fortune Warehouse in the will and the relationship between Tom and Allan becomes very cold because of his "happy - go - lucky" attitude . Allan is well known for his sharp rebuttal against George's insults and his well - rounded personality . After this season (1978--79), Hammer was fired from the show cast, and Mike Evans returned to the series in the fall of 1979 . After that, the way it was described with Allan's writing out of the storyline that he was residing in Minnesota . Allan was also chosen to be his niece, Jessica Jefferson's, godfather upon her birth, but Allan supposedly had gotten snowed in, so Harry Bentley was chosen as the proxy . </P> <P> Florence Johnston (Marla Gibbs) is the Jeffersons' sassy, backtalking, wisecracking maid . Her first appearance is actually in the pilot episode, when she was interviewed and hired as the housekeeper for the title - bearing characters . Although her job is supposed to take up most of her time, she is flat - out slothful, using very little energy or effort to clean the Jeffersons' apartment . She regularly bickers with George . George, who pays Florence's salary, repeatedly complains about her laziness (and cooking), and he gives her a very small paycheck . Several times he was on the verge of firing her, but Louise, who thinks of her as one of the family, forces him not to . Originally a recurring character, Gibbs later became the core of the series, becoming a series regular, appearing in 207 of the 253 episodes . </P>
