That's interesting about the ploughing into mounds, Judith. I suppose it made some sort of sense then. As to the bombings, there were certainly people killed at Jillcot Rd and Rangoon Rd, so no doubt a few landed a little further along.
There were people killed in Alston Road & Cornyx Lane too, which would be the result of gas works bombs missing their target rather than bombs aimed towards the airport (though the 2 are very close together) -

Elmdon Hall seems to have been in decline before the Home Guard took over use of it, shame it was demolished though, but it would appear to have been too expensive to repair & I don't suppose there was a use for it with no family wanting to take it on. The rectory survives though, and the gate house (which, as a child, I wanted to live in).
There is a great book, if you can track down a copy, called Damson By The Pound by Stanley Beavan who grew up around the Damson Lane/Lugtrout Lane area who had an uncle that was a grounds keeper at Elmdon Hall.
