That's just a classic dud transcription. Extract of original attached.
The first two names are clearly Hugh and Agnes, not Andrew and Ann, and George Phimister is in a separate household, presumably the son of the postmaster and acting for him while he is away from home. Agnes Jr is a daughter, not a son, and a teacher, not a scholar. Hugh Jr is a baker's apprentice.
This is why you always have to look (eventually - I am as guilty as everyone else of not having got round to viewing all mine) at the original and not rely on someone else's misreading.
