Our ancesters

I am the g.g.g.grandson of Too Has Ka, also known as Tyee William who was tyee to the Chetco indians when they were sent to Siletz in the mid 1800s. I have very little on him, history wise. I don't even know when he died or were he is burried. If anyone can help with any information please let me know? thank you,
