My surname's original form was Ui Lúinígh. It means, "armed with a mythical spear that the gods use to kick ass as needed." With this, I am well pleased.
I need to hunt down more about my mom's side, but as I already found out years ago, Iranian genealogy is very hard to track down in the US. I do have a list of women on my mom's side about five or six generations back- one of my great uncles wrote it up and gave it to my mom when I was born- but there's little else I have beyond that.
