One other thing that has disappeared from common use(although I have seen it done among some "higher" circles still) is using the husband's full name for the wife here in the UK.
So if you have a man called "John Bridgerton", his wife would be referred to in certain circumstances as "Mrs John Bidgerton". Like you'd get an invite to the King's Ball, and it would say:
"Hereby inviting:
Mr John Bridgerton and Mrs John Bridgerton"
