unknown relation found

Every year, 2nd Sunday in August, we went to Brecon Jazz Festival - until the car broke down in our drive! From then on we stayed for the weekend. That first Friday afternoon, we arrived at our guest house and, as I settled down in the garden with a cup of tea, another couple of guests arrived. "I'll join you in a minute" the lady said. When she did, the conversation went as follows : Millie : We're from Barry. Have you come far? I said : Gloucestershire. Millie : My husband comes from Gloucestershire. He was born in Berkeley and went to Dursley Grammar School. I said : My husband was born in Cam and he went to Dursley Grammar School. Maybe they know each other. What's your husband's name? Millie : Norman P I said : Any relation of Charlie P? Millie : Yes. He was his uncle. And I said : Well, he married Margaret T, and that's John's aunt! Millie and I could have chatted all afternoon without ever following that line of conversation. The fact that in eight sentences we had established the connection is just amazing. John and Norman soon joined us. Charlie and Margaret P's son Pat was, of course, a cousin to both of them - but neither had known of the other's existence until then. The conversation soon ranged from reminiscences of masters at Dursley Grammar School to Pat's superb train set that both had played with and the year of the dreadful thunderstorm at Berkeley Fete which had near drowned them both. Since then, we have become firm friends and ..... On those earlier Sundays at Brecon, we had picked concerts by The Riverside Jazzmen as ones not to miss, without knowing that Norman was the trumpeter and musical arranger in that band - and Millie and Norman's son Vic was the banjo.
