The ancestry of the Rahimtoola Family can from the data available today, be traced to one Adam in Jamnagar City.
There was and is, to a certain extent even in present times, the general practice of abridging names or giving nicknames, and Adam, it appears, became popularly known as Adu.
"Mr. Hooseinally M. Rahimtoola had round about 1940, prepared some Family Notes. He had also kept, prior to his departure for Africa, some rough notes with his younger brother Suleman and, later on, some more notes with his son Jaffar.
This paper is an attempt to put together the available data for future generations of the family. It is hoped that the younger members of the family will periodically up-date this paper."
