On the outbreak of war Mount House School at Plymouth was urgently looking to evacuate. Jocelyn’s son Peter was there, and Penhellis was offered as accommodation.

They moved in and “Monica” and her grandmother Margaret moved to a bungalow at Mullion. The paddocks were ploughed up to make football pitches, but due to the unevenness of the land, they played rugby instead. Later, the school found larger premises and moved to Tavistock where they remain to this day. The American Army then took over Penhellis and later Margaret moved back and was well looked after by the remaining troops. For many years after the war she received visits and Christmas cards. A tree was presented and planted at Penhellis, but sadly grew to an enormous size and had to be felled. Margaret died in 1964 and is buried with her husband at Breage.
