army records pre first world war

[Rustidge]

My gg grandmother Eliza Greenwood eloped with a soldier from Colchester barracks (James Stott)between 1867 and 1872. They had 2 children 1 born Warwick England @1872 and 2nd born Waterford ireland 1875.
James died in Ireland and Eliza Stott remarried in 1877 in Rochdale Lancashire.
I found birth of Fred G Stott in Ireland @1875 but am unable to find other information on what James did there. Cant find their marriage or James death. But have later records census etc for Eliza and family 1881.
