Blackett’s Creek in Prince Edward Island, Canada is named after William Blackett who farmed there. William’s son, Walter William Blackett later moved to Cape Breton, Nova Scotia, where his son, William Blackett (see image) acquired a farm from his father and built a house on the shores of what is now known as Blackett’s Lake.
