I went and checked the Tutelo form. There is a 3rd plural suffix /-hele/ that has numerous allomorphs including -hele, -hle, -hela, -hne and others. And re the Hochunk forms, don't forget that *-a > -e after velars in final position, e.g., Proto-Siouan *ru:tka 'dove, pigeon', WI ruucge' and other similar forms. Bob
