I have access to many sources related to Upper Canadians during the War of 1812: militia payrolls, war loss claims, orphan pensions, wounded pensions, 1875 pensions, militia land grants, a prisoner of war and parolee register, etc. I also have access to unpublished name indices to some of these sources which make finding specific people easier. I will do look ups for free but may charge for some document recovery services.
