I found several ad listings for hair preparations under the name "Coudray." In 1873, L. Shaw was listed as the Agent for F. Coudray's Magic Hair Tonic. In the 1878 National Druggist, Shaw advertised "F. Coudray's Aurora, or Golden Fluid for bleaching any dark color of hair a fine golden blonde." Mrs E. M. Morey, of Providence, Rhode Island, also advertised "E. Coudray's Oils for the Hair" in 1872-4. Coudray's Oriental Pomade was listed for sale in the 1880 Woodward, Faxon & Co. catalog. All these products were probably from the same Proprietor, but I don't know where they were from.
