Oh dear..... I haven't read every post, but I find all this a bit of a storm in a tea cup..... As lots of people have said, does it really matter whether some people choose to conform to the cultural norm.
I happen to like tradition (shock alert..... my DH asked my father for my hand in marriage before asking me!!! How funny and old fashioned is that!! It really made my father happy though and I thought it was sweet, and yes, my father 'gave me away'). And yet my education, my career, my relationship with my DH could not be more equal.
As it happens I didn't change my name immediately (we got married 7 years ago and I just sent my passport off last week to change my name to DH's), so I've had a fair amount of time to think about it. Funnily enough, I've never really found it a problem using either name. The issues re bank accounts are irrelevant - soon after I was married I gave my bank a copy of my marriage certificate meaning that cheques could be paid into my accounts in either in my maiden or married name, and I've found it the same with everything else along the way - I have used whichever name was convenient at the time. It was a bit annoying once when my PA booked a flight in my married name soon after I got married as she assumed I had changed my name, but even then it was fine although a bit annoying to have to take my marriage cert with me on a business trip!! Most of my friends and family always refer to me as Mrs DH, and I AM Mrs DH, whether or not I had formally changed my passport.
So why am I changing my name now 7 years on?? Well to be honest it's the family unit argument mainly. In particular I want to have the same name as my 3 children. Also I have grown used to being called by DH's name and I like it! I suppose some people would say why did we give the children DH's name not mine but I never really gave it much thought - they had to have one or other name and culturally it is usual to give DH's name, there is always a standard system to these things, (although I'm glad that people can choose to do it another way if they want to). I have friends who all went double barrelled to keep both names, but personally I think that's a bit of a faff and generally too much of a mouthful.
I have two friends who made a big point of staying as Ms Maiden Name after they got married and to be honest I find it a bit of a bore to have to remember that all the time when addressing envelopes etc (well it's only really once a year for Christmas cards!). It just seems so contrived, what does it matter if I write Mrs DH on the envelope? They are still who they are whatever I write. As I said, for the last 7 years I have kept my maiden name, but I couldn't have cared less if people addressed me as Mrs DH (which they all do anyway).
I simply don't see that following a (yes, probably outdated and definitely patriarchal) cultural tradition of nomeculture has any detrimental bearing on a woman's current place in society. Surely people just see it as a useful tradition rather than any sense of being owned by / controlled by / subservient to the men in our lives.
Anyway, to those of you who are getting married and are unsure what to do, just remember you don't have to make a decision immediately - leave it a year or two and see if you grow to like using your husband's name, then you can change it formally later if you want to.
