what?!? This is the craziest thead I have read in a while. My middle name is Catherine that is why I am here. But Woah nelly! Why were you so excited that your name didn't directly mean pure if you really don't think that the meaning of names coincide with a persons personality at all. I shouldn't have affected you either way. The meaning could still mean pure. Why do you think that just because it says on this site that the Romans were wrong, that they actually were wrong. I think that they could have been right. How do you know?It isn't that far of a stretch to be derived from Katharos. It seems a lot more likely than the other derivatives that they have in the meaning.
