There are 2 different stories to who I was named after. My mother tells them both, so I think it just depends on who she's talking to.

I am a middle name person (I go by my middle name). My first and middle names were the names of a set of twins on "One Life to Live" (I think). One was evil, one was good. . .it's a daily battle which one wins with me!

The other story my mom tells is that both names were in a book she was reading, and she liked them both. There's no one in my family named either one, so no family thing there.
A funny, though: I'm from a small, small town, and my mother grew up in the even smaller small town right next to it. They used to run a "gossip column" in the town paper and the writer would give a "shout out" of sorts to the people who had had children. My grandfather (mom's dad) called the gossip lady
as soon as I was born. He was so excited about it, and when she asked what my name was, he couldn't remember. He told her that it was 2 names (I just use 1) and that both of them were "nature-y". He said, "Oh! I know what it is!! It's "Heavenly Branch"!" So, my birth announcement in the gossip column ran as Heavenly Branch!!
DH & I have boy and girl names picked out too. We will use DH's middle name as a middle name for the boy, and then a name I like for the first name. For the girl, we're stuck between 3 for the first name, and the middle name of my favorite kid I ever coached (who is like a daughter to DH & I) as the middle name.
