I don't think so. This is from Goes to It
when Madge and the staff are talking about leaving Guernsey:
Madge Russell laid down her work. ‘Jem and I discussed it last week,’ she said gravely. ‘We knew that it must come up. He insists that I shall take all our nurseryful to England as soon as possible. In that case, I can scarcely leave the school here. As Hilda says, it’s a case of other people’s children. If ours go, then they must go too. Jack Maynard agrees. He is sending Joey and the Triplets away as soon after Easter as possible—even, it may be, before.’
‘Joey won’t like that,’ said Miss Wilson shrewdly. ‘She loves her pretty home. And where will they go, Madge? Pretty Maids is out of the question now, I imagine.’
‘Oh, quite impossible. If the old folk had been living, it would have been the obvious solution, for you know how they adored her, and she loved them dearly. But now that they are gone, and Mrs Robert and the Major are in possession, it’s out of the question, as you say. None of the Maynards have ever liked poor Lydia, and she is a most uncomfortable person, I admit. She has always resented the fact that, since Rolf’s death. Jack is his brother’s heir; and since the coming of the Triplets, it’s been worse. Bob Maynard wrote a charming letter to Jo, but Lydia has taken no notice whatsoever.’
Also, after Bob's death in Rescue
, Joey talks about visiting Pretty Maids to sort things out so it doesn't sound as though the house is being used by anyone else.
