So as of recently, my name is my name.
That would be fairly straighforward for everyone else, but no such simple things in my household.
I married my Transsylvanian Hungarian wife, now Juliánna Juhl-Johansen Zölde-Fejér, in September of 2007. We merged our names, and my Juhl-Johansen and her Zölde-Fejér came together as something which was ours entirely - and, of course, as some have pointed out, would be a challenge to pronounce correctly in its entirety anywhere. Be that as it may, it is ours, and it is not likely to be lost in a crowd.
However: A while after we were married, she had to get a new passport. And so, she ran into some difficulties. As it turns out, the Danish naming conventions - which had obviously been used, because the state church is actually the name registrar in Denmark - offered some challenges. Thing is: In Danish, you have a first name and a last name. Anything else is your middle name. Not so in Romania - Transsylvania, which was a part of Hungary, is now part of Romania, and no, it is unlikely you can come up with a Dracula joke we have not heard - They have first names and last names. So her Danish name document was rejected. After a bit going back and forth with various authorities on this, we simply pulled out my old last name, and after that was done, I was registered in the public registry as Morten Zölde-Fejer. They had also pulled the last accent.
After our return to Europe after living in the States in 2010, we started the process with my wife applying for a Danish citizenship. Since she was from a Hungarian family, she was not particularly connected to her Romanian citizenship; she had also never been part of the country of Hungary, so being a part of this country seemed equally irrelevant. We had come back to Denmark and decided to stay here, at least until the children are older.
And so, she became a Danish citizen recently, after a longer process. And at last we could actually go through the process of syncing up our names! So the name you see at the top, here - it is actually my name now. Again. Still. At last.
