I discounted the Chatel/Chateau connection as Bolbec Castle in the middle of the village was not built until the 13c and the name of the Chatel Stream appears to pre-date that. Of course there could have been a small castle or fort thereabouts earlier but no archaeological evidence appears to have been unearthed. Anyway the Bolbec Castle site has its own stream, a spring named Sweet Alice. Your suggestion of a possible "cēto-" = "woodland" derivation is interesting as woods would have been features on the otherwise sparsely wooded chalk/limestone hills of the area.

Or could it have come down from Celtic "cēto-" = "woodland"? Or related to "castle"?
