Term: Baraboo [origin of place name]
Definition: 1) After a French settler in that region, Jean Baribault. 2) It was claimed by John de la Rond, who settled at Ft. Winnebago in 1828, that the Baraboo river was named for Captain Barebeauy, who was with "Morgan's Expedition against the Indians" and wintered at its mouth.
Also, it seems probable that the name may be a corruption of a French word or phrase... the word "Brebeuf" might possibly leave its shadow behind as Brabo or Baraboo.
