In OH's family of Ag Labs a great-aunt owned a big house with lots of nice furniture etc. (according to elderly relative who used to be taken there as a boy) I think the rest of the family rather looked up to her - my M-I-L was named after her. Everybody told me she had married into money.
In censuses she was a dressmaker

then was in service in London, then owned the 'big house' in Norwich
where she was living on her own means 
, then she married a much younger man who had been one of her lodgers

so she owned the big house before she married him.
Although I knew 'dressmaker' could be a euphemism, I hadn't put two and two together - but now I'm beginning to wonder.....
