Anyone with information on Colonel Thompson, formerly commanding officer of the 96th Regiment at Dumdum and Dinapore, West Bengal, (East) India -- his daughter, Mary Hannah (Poppy) Thompson (born ca. 1854, died 22 February 1894) was married to Dr Hamilton Mitchell, the "Brigade Surgeon of Londonderry"? Dr and Mrs Hamilton Mitchell lived at Lanowlee, Clooney Road, Waterside, Londonderry. Many thanks David Mitchell Cape Town South Africa
