I threw a list of names at my mom and let her pick one that she liked. Surprisingly, she picked Luca, and not the name that she had planned on calling me if I'd been born male. "Now-a-days" I prefer Luke or Lucas, but she still refers to me as Luca, haha. I guess it'll just be a nickname, or I could tell people that I went by Luca as a child... Idk.
My new middle name is just one that I really like. I'm a spiritual person and use nature to connect with that, so I chose a nature-related name. This is subject to change as I haven't changed it legally yet and may pick one that's more related to one of my birth names. I doubt I will, though.
