Tck13, your signature, I don't know how much (or if) you care for accuracy. It was Chief Sealth. There has never been a tribe member named "Seattle". Probably could have PM'ed this but couldn't waste an opportunity to try and derail this thread, which is stupid.
His name was spelled several different ways not just "Sealth" as you say. Seathle, Seathl, See-ahth, or Seattle. I chose Seattle because it seemed like the easiest to spell at the time.
