From what my mother got from my Great-grandma. She lives somewhere in Texas at the end of her life. I was about 8 or 9. I remember her saying that the original name was Danopolis, shortened to Danos when they came from Greece. At some point they had several plantations in LA, and when my mother was doing the fam tree we were the only Danos' in Denver, CO. There are several Danos' in Denver. Both black and white who were doing the same work on the name. That's all I know. If you want more ask and I'll try to remember.
