Hugh,
Edward Tulloch died in 1892, a Colonel (retd) Bengal Native Infantry.
John Tulloch, Edward's father, appears to have been Adjutant with the 22nd Regiment Bengal Native Infantry when they landed in Java on 4 Aug 1811, part of the expeditionary force (HEIC Java medal). While in Batavia he met, and married, Jacobina, daughter of Dutch East India Company official Abraham Couperus. The Tullochs remained in Java for about six years, until 1817. John Tulloch was a keen botanist and it may have been through this interest that he became friends of the Raffles. John and Jacobina Tulloch's eldest son Stamford William Raffles did indeed have Thomas Stamford Raffles and his wife Olivia Marianne Raffles among his godparents.
John and Jacobina Tulloch had eight sons in the armies of the HEIC and their surviving daughter married an HEIC officer, George Palmer Whish.
As for John Tulloch's father, Alexander Tulloch (c1754-1832) of Charles Street, St James's, Westminster, he appears to have come to London from NE Scotland about 1776. In London he was a coal merchant. There is a memorial to him in St James's Church, Piccadilly. We have no documentary evidence of exactly who his parents were but his unmarried sister lived in the Nairn area. It's not so far from Inverness, by sea!
As for Major General DDC Tulloch (1903-1974) of Chindits' renown, he was a grandson of Edward Tulloch's brother Alfred (1829-1905). And, talking of godparents, my husband's godfather! I would be very interested to know your connection with him. What was your grandfather's name?
