John Horrocks Whitehead, a partner in the trading firm of Shaw,Whitehead & Co.
John Horrocks Whitehead died at Singapore in 1846 aged 36 years. the same age as his uncle the cotton tycoon had reached at the time of his death. He is mentioned in the Singapore newspaper regarding his involvement with the church, St Andrews I believe, just near the Raffles hotel, and I believe he is buried in the churchyard.

John Horrocks Whitehead is buried in the old cemetery at Fort Canning in Singapore. A tombstone was reportedly erected for him by his good friend and business partner, the wealthy philanthropist Tan Tock Seng (1798-1850) upon which he inscribed "as a token of affection on the part of a Chinese friend, Tan Tock Seng."

Some of the tombstones have been embedded in the perimeter all, but I could not find that of John Horrock Whitehead
