Wasn't Ho John on M.A.S.H. in only a couple of episodes and then never seen again? (I think so). So since he wasn't a regular character I'm not sure he should count.

Free Spirit (1989-90) - Winnie Goodwinn (lives in, cares for the kids)

Also, a female household servant appeared briefly in the first season of Leave It to Beaver, IIRC.

A maid, Minerva, appeared briefly in the first episode produced, "Captain Jack." It aired as the second episode. It was postponed due to CBS's problem with the toilet tank shown.
