Thinking about my middle name, which I passed on to both my kids, since my partner passed on his last name... but it feels really perfect that I have this middle name which can be passed on, used as a backup name or primary or placeholder name if my kids ever decide they hate their (more gendered) first name. I love that it kind of works in all these ways (plus it can make your first name an adverb for better or worse)
My middle name is Leigh
