Cugnon comes from the following:
Chez (Latin casae “at home” = French chez) Congidunus (Celtic surname, cf. the Breton king Cogidunus cited by Tacitus in Agricola, or the Gallic Conconnetodunnus, cited by L. Roger; this name contains the Gallic duno “pregnant” and the Celtic adjective * connios “clever, end”).
