I am trying to get more information on one of my ancestors, John Cashman (b. abt 1837 Cork, Ireland) who served during the Crimean War. He migrated to NSW Australia before 1868, where he married and died. According to an article in a local newspaper in 1908, he served in the Crimea participating in the battles of Kurtz, Balaclava, and Alma. It does not list what regiment he served in.
Would anyone be able to tell me where to look? Most references need a regiment or unit to start with. Any information would be greatly appreciated!
