Nice try, OP, but American homes would have had a housekeeper before a butler in the small staff you describe. It was not seemly for a small household to mix males and females the way you propose.
You also appear to be completely clueless about what a maid's job actually would have entailed in a small household. A house where the lady had a full-time nanny would have had a life requiring a lady's maid (upstairs maid, if you will), and a downstairs/cleaning maid performing both lady's support and cleaning would not have been let go.
Plus, the "butler" (again, this is a false set-up, and a housekeeper would have stepped in to assist the lady in a way the fictional butler couldn't and left the cleaning to the downstairs maid) would not have had enough to do.
The least you could have done was say that you grew up in a three-staff living-in house, with a combination chauffeur, gardener and all-purpose man, a cook, and a housekeeper, that a cleaning maid came in three times a week and also came in to serve at larger luncheons and dinners, and that of course the housekeeper had a woman in twice a week for the laundry. And you could explain a nanny by implying your mother had a morphine addiction.
I grew up in a house with a service of five, and all the ladies ever seemed to talk about was their clubs and their philanthropy and the trouble they had with their help. Ours were all Irish and German - I'm old. Housekeeper (Mrs. Davies), Downstairs Maid (who also did scullery work), Cook (Called "Cook"), Upstairs Maid (my mother's help with clothes, and she did our laundry, too), and the House Man, who did the yard, drove, ran errands, fixed things, and answered the door at parties and lunches and dinners. He was married to the cook. They lived in the carriage house, and the rest slept on the third floor, where the nursery was as well. So that's the real set-up for what was looked down on by my mother's friends as a "small staff for a modest house." But we also had a couple who lived at the country place my parents kept, and none of the other families had THAT.
