I am sad so just went through the married women on my fb. 25 of them were married before I knew them and have the same name as their husband so I don't know whether they took their husband's name or vice versa although I suspect the former.
30 have taken their husband's name.
10 have kept their birth name (one has a husband who changed his to her name).
2 (including me) have mutually changed their name (so both partners double barrelled).
3 have double barrelled but their husbands haven't.
So out of the 70, probably 55 have taken their husband's name so it is pretty ingrained.
