Sue, These may be complete red herrings, but would seem to me to be worth investigating. 1. A Margaret Robinson, daughter of John Robinson, Pte. Royal Scots and Elizabeth a native woman, was born on 24th December 1818 and baptised at Secunderabad 27th May 1819. 2. William Henry Wilson, bachelor, Pte. Sappers and Miners married Margaret Robinson, spinster, Indo-Briton, at Bangalore 30th June 1834. 3. Margaret Wilson, 8 months, daughter of William Henry Wilson, Sergeant Sappers and Miners, was buried at Belgaum on 24th November 1838. 4. Henry George Wilcox, Corporal, Bombay Engineers, married Margaret Wilson, widow, at Belgaum on 21st January 1839. I don't have a death of William Henry Wilson, but the above may be worthy of further research. Even if they can all be discounted in the end!
