Hello, I am also a Heppleston. My family hails from Pontefract Yorkshire. My Grandfather was John William, his father James. James was a confectioner, and when he retired from the candy business he purchased a pub in Rawcliff Bridge Yorkshire, the name "Black Horse Pub" It is still there but in poor condition, and not open.
My grandfather William was a Veterinarian, trained at the University of Toronto, prior to the Vet college being moved to Guelph University in Guelph Ontario. I would be pleased to share what I have if anyone thinks they might have a link to my line.
