The German Colonial Handbook 1903 mentions "Ibrahim Hashim" and his brother(?) "Dharamshi Hashim" a merchants of Utensils and canned goods, resident in the German East Africa capital of Bagamoyo in 1903.
Among the prominent Indians of the (Khoja ed.) Ismaili community, I remember a number by names, and I shall enumerate some of them. Bandali Remtullah as Mukhi was their representative. Others were Alidina Visram, Ibrahim Lila, Kanji Hansraj, the heir of Jan Hansraj, Dhalla Bhimji, Daramsi Haschem, and Jaffer Dossa Thawer, Jaffer Remtullah, Pardan Mohamed, Abdullah Allarakia, Merali Remtullah, Jaffer Somji, Ali Siwji, Ismail Jiwani, Ali Somji, Ibrahim Hasim, Saleh Siwji, and many others.
In 1899, there were 401 brick houses in the town of Bagamoyo, belonging almost entirely to members of the (Khoja ed.) Ismaili community. In addition, there were 2431 native houses with makuti roofs, built along streets which were already comparatively straight in those times. Besides, there were two large and magnificent houses which had been given as a present to the German administrative authorities by the Indian Sewa Hadji.
