Just a query about that birth - it was September quarter 1945 so therefore the baby was born July, August or September of that year. Meaning it must have been conceived October, November or December 1944. Therefore it can't be right as you said "William Baker was killed at Arnhem in Sept 1944" Even if that baby was born in June and not registered until the following quarter, I doubt if William would have known Peggy was pregnant before he died.
