Vita .. the information that I brought up didn't bring up a birthdate .. that was just what I put in and I think the +was 10 years leeway. The dates it brought up were - enlisted April 1813 & he had left the troop by 31/5/1816, you would need to find his actual enlistment and or discharge to see his age. The mods in here will know if they are available online. I think some records are at the TNA.

For my OH's military ancestor history, I had Kevin Asplin a military researcher look at the actual records of musters etc, but before you paid for that you would need to know for sure that the Thomas Headland at Waterloo was your ancestor Thomas Headland.
