Mamool"s two sisters were married to his wife"s two brothers, Asgar and Ashraff "Choate" Ali, a situation that led to a decades-long family feud over doubles. Deen writes that, concerned for the welfare of his extended family, Mamool brought his brothers-in-law into the business. However, trouble started when Choate began to sell doubles in Mamool"s territory instead of venturing out on his own. By contrast, Araby Ali, Choate"s grandson, who today sells doubles in the town of Barataria just outside the capital city of Port of Spain, claims it was instead his grandfather who started the business. Deen categorically rejects this claim, going so far as to include pages of "testimonials" from elders and historians verifying Mamool Deen as the doubles creator.
