I changed my name on marriage and it does sting a bit to be criticised for it. But I have a few things I would like to throw into the discussion.
It is much much easier to not change your name now than it was in the past, even the quite recent past. And it is much easier to do it in more progressive places. I'm from rural N Ireland which is much much more conservative than the rest of the UK. It's simply not the norm at my children's school for parents to not share the same surname, and it's fairly rare for parents not to be married to each other - there is only one child in my daughter's class of 30 who doesn't live in a 'traditional' family set up.
I only know one woman who didn't change her name on marriage, a work colleague. Her manager refused to participate in her performance appraisal and sign off her payrise because she said that as a born again Christian, she believed it was my colleague's legal duty to take her husbands name and she refused to use the correct name. So that resulted in months of grievance procedures and disciplinary issues (for the manager) and a lot of 'why don't you just use your married name and get your payrise, it's easier that way?'.
In my own case, I considered not changing my name and my father sat me down and told me how ashamed he was and that he thought he had raised me better. That it showed a lack of respect for my husband to be and that I would be starting our marriage by humiliating him and my parents and that it was a public statement to the world that I cared more about myself than anything else.
On the other hand, I had a very unusual name and I hated it, I craved the anonymity of disappearing into the crowd. But then, that was my poor self esteem that caused that, I was ashamed of existing, ashamed of who I was. I was bullied at school and told I was ugly and that people disliked me and found me annoying. The opportunity to change my name felt like an opportunity to be a new person. That felt very attractive.
If I was getting married now, in 2016, I'm certain I would keep my name. But 20 years ago when I had to make the decision, it was all just too much for me.
