Some of my ancestors are said to be United Empire Loyalists from the U.S. who immigrated there from England. Do you have any possible dates for these Loyalists entering Canada and where they may have settled?

The migration of Loyalists from the USA to Canada started in the mid 1770's, most migrated first to Nova Scotia (and what is now New Brunswick), then west to Upper & Lower Canada as free land was offered. Loyalist settlements in Upper Canada were mostly in Eastern Ontario (in & around Kingston) but Loyalists can also be found in other areas of what is now Southern Ontario.
