I'm not sure if this is the correct place to ask this question, but my parents grew up in Chattaroy Washington, and I'm curious what the word's origins are. I've done a little searching and I can't even determine what language it has its roots in. Any help would be appreciated.
It appears to be a word in a Siouan language, though Chattaroy, WA was not founded until the early 1880's.
"CHATTAROY. The name has been recorded since 1775 (as Tatteroy, Tatterio, Chatterio, Chattarawha etc.) The term referred to the Big Sandy River as well as to the Indian group called the Tutelo, of the Siouan linguistic family....There is also a Chattaroy in Wash. (Spokane Co.), established in the early 1880's."
