mother-in-lawed

'I will not,' said Fanny, without answering the question, 'submit to be mother-in-lawed by Mrs General; and I will not submit to be, in any respect whatever, either patronised or tormented by Mrs Merdle.'

Little Dorrit Charles Dickens 1841

I implore you not to submit to be mother-in-lawed by Mrs General, without asserting it in making every one about you as uncomfortable as possible.
