Interesting discussion! I'm struggling with the name issue too. I want to legally change everything - gender, first/middle/last name. I actually wanted to change my name when I was about 12/13 - well before I knew I was trans, which is a recent realisation now that I'm pushing 40. But I didn't want to have my dad's last name for various reasons, and I actively disliked my given names. My family called me by my nickname, and I wanted to change it to that. But it wasn't till age 16 when I made everyone call me by my nickname, even in school (even though I still had the same legal name). I haven't liked my name all my life.
Now, I'm trying to figure out my new legal name too--as well as my pen name. In my dream world, I'd love to have them both be the same thing, but I'm trying to decide if I want to be out as trans guy in my writing world. I'd really like to, just nervous, I suppose. I'm debating to have one of my names be an androgynous version of the female nickname that I liked. I'm actually writing under Hugh plus my new last name that I'd like, and a close friend of mine really liked the name Hugh too. So I think that's a strong contender for first name, and an androgynous middle name.
If anyone has struggled with pen/stage names, and having different, new legal new names, I'm interested to know more - happy to start a new thread so as not to derail this one if anyone else is interested in the topic. I'm just wondering about implications for my profession, but as a writer and creative I'm happy to be 'out'. My only worry is for jobs and also international travel if I have a public profile as being out as trans.
