I am researching 3g grandfather Alexander Fraser, born 1791. He was in the 2nd battalion, 49th Foot (Princess Charlotte). In the spring of 1816 he was in Barnet, Hertfordshire, as a recruiting officer, and was discharged on 24 Sept 1816 in Canada. I would like any kind of records that are available, or where to look, or where to write, for that kind of information. About all I know of his origin is that I think he came from Invergordon, Scotland.
