Kneeza Memory has gone looked it up and Heinz Kittendotf was a POW but he was interned at Bourton and Frankton Great guy.Talking of Stretton picniced on the steps of the War Memorial ( see how we lived it up) on the A45 single carriage then. Never saw a car from start to finish.
Yes, Heinz was at Birdingbury Camp (called Birdingbury for some strange reason, but was in Frankton parish on the edge of Dunsmore going down from Frankton village towards Birdingbury Station - which was ALSO in Frankton parish. Bonkers). It was, as you say, a POW camp during the war, and then a displaced persons camp after it, before becoming general temporary accomodation and then closing in the sixties.
Heinz set up the dairy business in Stretton, and a couple of my mates (one Stretton, one Bourton) worked for him in the early seventies on the deliveries.
He was a good man, and highly respected locally.
I was born in Frankton, but we moved to Cov when I was three, and I moved back there at 20, so know the area pretty well.
