My great-grandfather's name was Charles Caverley.He had five sons, to the best of my knowledge, and one of them was named Claude.His son Claude was born near LaPierre, MI and the family moved to Washington and lived in Walville, WA.Their house straddled the Pacific/Lewis county lines.
Don't know if it is the same Claude, but the dates are about right.
My grandmother was Bernice (Caverley) Towner, sister to Harold, Charles (Jr?), Carl Roland, Loyst, and Claude.Bernice was born in 1899, Carl and Harold served in WWI and "went over the top."(See http://www.rootsweb.com/~waskagit/swww1service1.htmlhttp://www.rootsweb.com/~waskagit/swww1service1.html)
