Two places -- The UELAC (United Empire Loyalists' Association of Canada) and the Land Grant / Land Peitition microfilms. The UELAC documents all known UEL's by descendants who join the organization claiming to be descended from a UEL. You can learn more about the UELAC by visiting their website (see links ). Land Grant / Land Petition microfilms are copies of the actual petitions and grant used to get land in Ontario. Most UEL claimants would state their UEL status in their petition.
