The German Colonial Handbook 1908 mentions the firm of "Somji Perdom" as a merchant in Iringa in 1908.
According to John Illiffe (see below), 1000 Indians & family followed German settler, Capt. Tom Prince to Iringa in 1898. But the the German Colonial Handbook Supplement 1904 omits this fact. So Somji Pardhan and his brother Ladha Pardhan may have arrived earlier but are recorded as being there in 1908.
