Maybe I shouldn't have claimed that Knife Chief was at Pike's council with the Pawnees. I tried to find what reference I have for that, and so far I have found only one vague suggestion to that effect -- something that George Sibley wrote when he visited the Pawnees in 1811; he mentioned a Skidi "head chief" and Pike, but he didn't tell his name. On the other hand, the father of Shartarish (also named Sharitarish "Wicked Chief") was there, and the son's portrait is the other Pawnee portrait by Charles Bird King on display in the Whitehouse library. There's already far too much misinformation floating around for me to be adding to it, so until I can find something that supports my notion that Knife Chief was among those at Pike's council, disregard it. As to the various Pawnees named Petalesharo -- I rummaged through my files and found a "Petalesharo The Younger" or "Petalesharo II", and the information I have about him indicates he was a member of the Chaui "Grand" Pawnee band, whereas, the earlier Petalesharo was with the Skidi "Wolf" band, which puts doubt as to a close (if any) family relationship between the two.
