For me Its quite simple. My brain decided it. Literally. The days I found out I’m trans, my brain would do this weird thing, where I could think about completely different stuff and suddenly my now chosen name would “fly” into my mental Field of View, like an asteroid in star wars or so. I told that name a close friend and 4 weeks later when we went to the club together I told him, that I will stick with it, because I didnt had a better idea (and it was the only name I really felt comfortable with).
Maria is really pretty!! I think Norah can similarly be considered religious but I like that it means honour :3
I wat just going to suggest that name, too :D its a really pretty name. It still sounds good in other languages, too (maryam in arabic, for example). Top 10 names imo
