There is something to be said for the unattested "eau glaise" 'clay water', like attested "terre glaise" 'clay soil', but both Ramsey and Stewart agree that Auglaize (and variants, implying "*"aux glaises"") is American French for 'at the lick(s)', literally 'at the clays', where wild beasts came to lick salt and minerals from the soil, and fulfilling the lacuna in standard French for a "salt lick." The spelling "glaize" is archaic (as in Cotgrave's "French-English dictionary" of 1611). In addition, in Arkansas there is a creek and mountain Glazypeau, from French "glaise à Paul" 'Paul's lick'. The assumed indigenous American (Algonquian) "'fallen timbers' or 'overgrown with brush'" has no support without any attested etymons supplied and would not match phonetically in the case of Shawnee.
