<P> Sondra Tibideaux ( née Huxtable ) , the eldest daughter of Cliff and Clair , did not appear on screen until mid-way through season one . She did not exist in the pilot episode ( Clair : `` Why do we have four children ? '' Cliff : `` Because we did not want five . '' ) In her first appearance , she is a sophomore in college , and Cliff notes her to be 20 years old ( episode 10 ) , making her birth year 1964 . She earned a degree from Princeton University and had intentions of pursuing a career as a lawyer , like her mother . She married her boyfriend , Elvin Tibideaux , in season four , and later gave birth to twins -- a boy and a girl -- named after Nelson and Winnie Mandela . More serious , earnest and responsible than the other children , Sondra fits many of the characteristics of the first born from a large family . Though she had her moments of bizarre thinking ( e.g. dropping out of law school to open up a wilderness store with Elvin ) , she 'd usually snap out of them relatively quickly . Because of her intelligence level and overachieving nature , she is looked upon by her parents proudly , but also is held to a higher standard than the rest of the children . Sondra appeared sporadically in early seasons of the series due to the character being off at college at the time . </P>
