Manor Farm (at the north end of Preston Capes High Street - now "The Manor") was damaged during this practice bombing, so it would seem possible that a hovel was also damaged. Manor Farm is on the south side of the castle mound - could this be Roundhill?
My only problem with the above is the actual address written by Frederick - he put Fawsley, not Preston Capes - and whilst the two places are lumped together for census purposes they are a good one-and-a-half miles apart geographically. Not sure why he would have put Fawsley if he was, in fact, resident in Preston Capes.
I have circulated this query to a few members of our informal local history group in the village to see if anyone can throw any light on the subject.
