Meredith Baxter, 64, has been an actress for more than 40 years. She is best known as Elyse Keaton -- the flower-child mom of Michael J. Fox's straight-laced Alex Keaton on program "Family Ties," which ran from 1982 to 1989. But baby boomers may remember her in her first sitcom, "Bridget Loves Bernie" on CBS in 1972, and her run on the show "Family" from 1976 to 1980.
