Lost Relative

My wife and I stayed in a small B&B in a small village by the Seine. We became friendly with an english couple who lived near Bayeux, who were there for one night only on their way home. The next day, we were going to Beuvron en Auge and since this was on their way home, we said we would meet for coffee at a cafe they knew. We had coffee but they did not come. We had a walk in the village and went into a creperie for lunch and soon spotted our new friends in the street outside. They joined us and during lunch, Bob asked me where my christian name, Lewis, came from. I told him it was my Grandfather's surname and he had been a playwrite who had one of his plays turned into a film. Bob stared for a moment before asking me some wierd questions such as did I have two uncles, Jim and Patrick, and an Aunt Betty. It turned out that Bob had been married to my cousin Anita, with whom I had lost touch with some forty-five years earlier.
