Given how the chiefs were named -- Chief (Adjective) (Bird) -- I can't say I'm too surprised that there would twice be a Chief Red Hawk. But I find it odd that there was twice a wounded outlaw named Glenn Bolton. It makes me wonder if that was an adaptation of a radio episode and they simply adapted it twice in different seasons.
