This is Winston Churchill's younger brother, Jack.
They were very close to one another, Winston kept a fatherly eye on him.
Like Winston, Jack was a brave soldier. He was wounded when fighting in South Africa, and also served in the First World War.
He was married to Gwendeline and their daughter married a man called Anthony Eden who was a very important politician during the Second World War.
