Bomma, the slave found in footnotes
In a letter of about 1148 from the Aden merchant Khalaf ibn Ishaq to the Jewish trader Abraham Ben Yiju, then living in Mangalore, a closing greeting is sent to Ben Yiju's Indian slave, later identified as Bomma, who was a Tulu-speaking man from the Mangalore coast. Ghosh rebuilds Bomma's life almost entirely from such asides in Cairo Geniza documents. Bomma appears as Ben Yiju's trusted business agent and near-member of the household, sent on trading errands to Aden, and he later accompanies the family back to Egypt.
