The following wording was sent to my maternal grandfather’s mother shortly after the Second World War. This was sent to a few people and, according to Caerleon.net was in thanks for taking in evacuees. Given that my maternal great grandmother lived on the south coast of England, I was surprised that this was something that she might be asked to do, but it’s a lovely thing to see.

I WISH TO MARK, BY THIS PERSONAL MESSAGE, my appreciation of the service you have rendered to your
Country in 1939-
In the early days of the War you opened your door to strangers who were in need of shelter, & offered to share your home with them.
I know that to this unselfish task you have sacrificed much of your own comfort, & that it could not have been achieved without the loyal co-operation of all your household.
By your sympathy you have earned the gratitude of those to whom you have shown hospitality, & by your readiness to serve you have helped the State in a work of great value.
