Appendix B, "Additional names of persons or families migrating from the colonies to Upper Canada", is a table that lists family names and the areas which they migrated from. Many in the list are from Pennsylvania. This table also includes a field, "Other information", that holds important information associated with each family name.
Summary
"The role of the United Empire Loyalists has always been a fascinating part of the history of Canadian development. But in 'The Trail of the Black Walnut' the reader will find for the first time a complete and absorbing account of what happened to one group of these Loyalists --the thousands of men and women knowns as the Pennsylvania Dutch who toiled through a trackless wilderness in search of rich limestone soil and the black walnut. These were the people who were to lay the foundations of a great Canadian province today known as Ontario." [from the book jacket]
