She snuck into town disguised as a man. Then, she masqueraded as a bag lady, an italian contessa and a newspaper columnist, all in effort to reacquaint herself with her long-lost family, the Capwells of Santa Barbara. When her true character, Sophia, the thought-to-be dead wife of C.C., finally emerged, all eyes were on actress Juduth McConnnell. Unfortunately for Sophia, she had not arrived soon enough. C.C.'s heart had been won by Gina DeMott, who became the second Mrs. Capwell in Sophia's absence. While actress Linda Gibboney portrayed Gina Capwell, she and Judith became fast friends. Linda, who has left SB to pursue other projects, often visits Judith at her ''cottage'' to catch up on things. They also like going out on the town. Both are single, fun-loving and enjoy each other's company tremendously.''We jiggle a lot. We laugh,'' admits Judith. ''On the set, we used to make each other laugh all the time, so it was really hard to get into the attitude, ''you are taking my husband; you are taking my son away.''. Adds Linda, ''And when we got toghether with Luise Sorel (Augusta Lockridge), forget about it!'' Judith's home, rumored to have been the pied-a-terrre of Charlie Chaplin, has a dream-like quality. With almost a denial of design, the place is open and illogical. Walls, stairways, ceilings and terraces are angled and arcaded for no apparent reason. The effect is astonishing, undefined , romantic and intrinsically seductive. ''It's a heaven in the hills'' says Linda, praising Judith's taste.
