I am trying to find information on LESLIE GORDON THOMS Second Lieutenant, General List, who died on Monday 21 February 1944. He is buried in Calcutta (Bhowanipore) Cemetery, India, Plot L. Grave 130.

I am also looking for information on SIMON DUNNE dod 5 May 1882, DOM 26 July 1852 to Susan Peat. His trade/profession is listed as Corporal, Sebundy Sappers and Miners, formerly in the E.I.C. Fort Artillery.

Are there any military records I can look up to ascertain date of birth, parents as well as country of origin? Any help would be appreciated
