The British have had a presence in the Indian sub-continent for many years. From the days of the Raj when the railways were first brought over to later colonialists, they lived and died in the foothills of the Himalayas and the plantations of the lower country. Hostilities took place on the Burma/India border and the graves of the fallen are recorded here.
Whether your ancestor died in India, Ceylon or Malaysia or even back home in Ireland, their memorial could live on in these records.
