I am probably in the Rabbit & Co group.
For me, getting married in the first place was to do with traditional ideals, fantasies almost, based on my grandparents. I always liked traditional manners and rituals too. Forms of address went with that. When I got married it was the most important thing in my life and I never thought of a life of just my own. I am still married.
I am not advocating that but describing how it was.
If I were doing it now I would probably keep my own name or make a mixture, I don't really see why the husband's surname should stay more than his first. The surname of the husband makes a wife especially chattel like so I cannot see much logic in being very upset with Mrs John Smith but not Mrs Own Name Smith as that only half eliminates the problem.
What is it they do in Spain? The wives and husband's surnames are different, each linked to their original family names, and rather complicated, but their system may be better.
And too, why have Mrs or Mr or Ms. They are all archaic and Royal garden-partyish.They are titles like any other and all link the person to some position in life
while without them a person stands as an individual.
Now, after this thread, I realise how sensitive young women are about it, I will be sure to address them as Ms Their Own Name + Surname in future, and not think I was being rude.
To older friends I shall probably carry on with the old form.
