A project dedicated to compiling a comprehensive history of the Bonnycastle families' origins in England and their descendants through Sir Richard Bonnycastle and Charles Bonnycastle who immigrated to Canada and the United States respectively in the early 1800s. These two branches of the Bonnycastle family have made a significant and interesting contribution over the years in settling North America. This project is being jointly developed by Angus. C. (Gus) Bonnycastle who resides in Rothesay, New Brunswick, Canada and John C. (Christopher) Bonnycastle who resides in Calgary, Alberta, Canada. Interested family members and interested parties are encouraged to contribute to the project.
