Shakespeare's Sister again does the business with a great post to generate comments:
"name changes in association with marriage and/or long-term partnership".
The comments board has been pretty active with everything from remarks about what Immigration Services require or encourage or expect to issues of dealing with family history.
For me personally I don't think I would let go of my current surname, partly because it is very uncommon (even in Germany where my dad came from), though I do have a residual love for the name Chapman which as recipients of my emails will know is the name I use there. It was the family name of my great gran etc, so I know a lot of the history of the Chapmans. That means something to me.
Of course, I could always be tempted into taking up another name --- say, Henshall or Tennant...
.... only kidding....
Cloud: you are the one for me (I'm just not about to extend that family name: your bro has already provided the requisite family additions and as I say, my name is too uncommon to let go of that easily!)
