Let's celebrate Mother's Day by hailing five actresses who have played moms on two (or more) different TV series. It's not as easy a feat as you might think. After all, many TV-mom stars -- Florence Henderson, Marion Ross, Roseanne Barr, Barbara Billingsley, to name four -- never again played that role in a subsequent series.
1. PATRICIA HEATON -- The gold standard: She has starred in two superb family sitcoms, as Debra Barone in "Everybody Loves Raymond" (1996-2005) and Frankie Heck in "The Middle" (2009-).
2. DONNA REED -- Starred as wholesome Donna Stone on "The Donna Reed Show" (1958-66), and later as J.R. and Bobby's mom, Miss Ellie Ewing, on "Dallas" (1984-85).
3. JUDITH LIGHT -- High-powered divorcee Angela Bower on "Who's the Boss?" (1984-92), followed by the not as well-remembered "Phenom" (1993-94), in which she played the mother of a teen tennis prodigy.
4. SHIRLEY JONES -- The matriarch of the musical clan in "The Partridge Family" (1970-74) also returned with a forgettable show, the comedy-drama "Shirley" (1979-80), in which she played a recently widowed mother of four (Rosanna Arquette and Tracey Gold were two of them).
5. LUCILLE BALL -- OK, so she was basically playing the same character throughout her TV career, but she did appear as a mom in three different series: Lucy Ricardo on "I Love Lucy" (1951-61), Lucy Carmichael on "The Lucy Show" (1962-68) and Lucy Carter on "Here's Lucy" (1968-74). On the latter, Ball's real-life kids, Lucie Arnaz and Desi Arnaz Jr., played her TV kids.
