Pilon is the surname of an old family, dating back to 16th century Bayeux, France. The name most likely comes from the French word for "chicken leg", as one of the earliest known Pilons was a butcher; pilon also means pestle in French.
There are many variations on the name, though all the Pilons are related. Antoine Pilon is the ancestor of most Pilons in North America. Pilon, Cuba, is most likely named after a Pilon who immigrated there; however, Pilon coffee products are most likely named after the Cuban city.
I went to Bayeux, France, to see where the Pilons came from. I also visited Montreal to see the house Antoine Pilon lived in and the park named in his honour.
