The house buyers do sound like like an odd family set up !!! No wives .. there would be a bit of a squash IF there were wives ! Definitely just the one son to live here with his daughter, he looked to be about maybe mid thirties and drove a Ute advertising Mechanics ! Mind you the Pom mother with her long blonde / gray hair looked only about in her mid 50s ! I did not see he husband except in the distance down at Dans. But the other son had 2 small boys !
I love Stratford on Avon too so interesting. S Moira and I worked in Stafford.... just north of Birmingham in the GPO college (My Mum got us the job as she also worked there for a time !~ ) while we were saving up to go to USA ! We visited Stratford a couple of times on our days off

Lots of interesting historical places

I did not pull the whole vine down but it does look a bit tatty today with some gaps !!!!!!!!!!!!!
