I mostly just had some rules for names I wanted to avoid: names of people I knew personally, names that sound weird/unusual in english or swedish (where I’m from).
I considered a bunch of names via the usual methods like baby name lists and random name generators but didn’t find one that felt right for me, until one day one just occured to me
The Owl House should be good for all ages
I’m not sure how old I was, I just remember where I was, and we moved away from there when I was 6.
My family wasn’t outright transphobic or homophobic, but they were generally insensitive and talking to them about it didn’t feel safe. I also reasoned with my limited knowledge at the time that there probably wasn’t much that could be done about it even if it was accepted.
So it took until I was 18 or so before finding out about other trans people, and about HRT (this was many years ago, before the current awareness)
I seem to remember them saying 10 was going to be the last one, too
