Dr James Johnston who had been born in Scotland in 1851 arrived in Jamaica in 1874. He started his Jamaican Evangelical Mission in 1876. Johnston created nine churches but the base of his medical mission and his religious assemblies were in Brown's Town. Johnston became the political representative for St Ann's Parish before he left to explore Africa. In the 1890s he took a team of Afro-Caribbean Jamaicans to England where they were equipped themselves to complete a 20-month journey of 4,500 miles through south central Africa. Their journey was photographed and described by a book published in 1893. Many of the photographs became postcards which have since become collectors' items.
