The account of Richard Davey, originally published in 1897 contains an earnest description of the Moslem and Christian nationalities under the Ottoman Empire. As the author makes it explicitely there is nothing like “Macedonian ethnicity”  but instead Macedonia at his time, contains a mixture of ethnicities, mainly Greek and Bulgarian.  Furthemore the account of Richard Davey mentions with stats the attrocities of Bulgarian brigands against the Greek population of Macedonia.
