i can put forward a candidate. According to the 1841 army index he was stationed in Corfu in 1841. His service record states he served 2 years 12 days in Corfu.So he could possibly have been there in 1843.I will check when the 42nd were deployed to Corfu.However,,this William served till 1858,and his intended residence on leaving the army was Stirlingshire.He also served in Malta,,Bermuda, Canada and the Crimea. He was in Bermuda in 1851.
