I went with Emilia for quite a while. I just love the sound of it, and I thought it resonated well with me. This was back in the days, pre-everything, when I was still questioning whether or not I was trans at all, and I thought I'd stick by it.
Then four years ago, my cousin had a baby girl and named her... yes, you guessed it. And from there on out I've felt increasingly detached from the name, feeling as thought it belongs to someone else and doesn't really fit me anymore. And now I'm fine with the runner-up name Thea, which is closer to my boy name. And I like it more and more. Still wondering if I should go for the long version (Theodora) or not though...
Elyra is just my preferred online nickname.
