We found this interesting mention of Sevagée (Shivaji) in the London Gazette of 1762. It mentions Shivaji seeking tributes from Surat, and follows up with the implications on Mumbai (Bombay).

Extract of a letter written from Aleppo;
November 19. 1672.
TWo days since we received Letters from India, written by the English President residing in Suratte, who acquaints us with the daily fears that have there, from Sevagée the Rebel, who having beaten the Mogul in several Battels, remains almost Master of that Countrey, and takes the boldness to write to all European Ministers in Suratte, that if they refuse to send him such and such immediate presents of Money (which as he puts them would amount to vast sums) by way of Contribution, he will return and ruine that City. That he exacts the like from the Inhabitants, who certainly would comply with his Demands, but that the Officers of the Mogul, being there hinder them. Which puts them into an extream Straight, and causes others daily to convey away their richesse; many also embarking and transporting themselves into other parts, to avoid the storm they fear will fall upon them.
‘Tis probable that the Island of Bombay, belonging to the English, will reap no smal benefit by these Broyles; to which place many Bannians flock with their Families and Estates. ‘Tis reported that that Island is now made one of the richest and pleasantest places in all India. ‘Tis said, they want nothing but some industrious English hands, and that it is intended to engage what numbers may be, to come and inhabit there with a promise of many considerable advantages, especially that of Trade in all Asia, and to Africa, as far as the Cape of Good Hope, and to the Gulfe of Persia, and several islands in those parts.
