The Calpins are thought to be the biggest band of brothers to have fought in the conflict, which left more than 700,000 British soldiers dead between 1914 and 1918.
Amazingly with just one brother lost, the family mirrored the fatality rate among British soldiers at the time which was just over one in ten – 11% – losing their lives.
The Calpins' extraordinary contribution to the war effort earned public thanks and congratulations from King George V and the prime minister of the day Herbert Asquith.
Their names were trumpeted in a recruiting drive at the time and even broadcast in local cinemas in their home city of York.
However the men, many later buried in unmarked graves, have no permanent memorial and their descendants are now calling for them to be honoured in their hometown.
The brothers, and their ages at the outbreak of war, were; Reservist John, 37, soldier Patrick, 36, infantryman James, 33, infantryman William, 32, infantryman Martin, 29, infantryman Thomas, 27, infantryman Arthur, 24, gunner Henry, 22, sailor Ernest, 21, and sailor David, 18.
The family's only fatality was the eldest, John, 39, who was gassed in the trenches in France and died in 1916 after being transferred back to a UK hospital.
His grave, in a remote area of a cemetery in York, is the only place that any of the men's service is commemorated.
It is thought the rest of the men, after returning to poverty following the conflict, were buried in unmarked graves because the family could not afford the expense of headstones.
Today, as Britain prepares to honour all those who served in the First World War on Armistice Day few have ever heard of them dubbed the "forgotten brothers" by relatives.
Two generations on, Michael Calpin, 68, is calling for a permanent memorial to be erected amid fears their place in history will fade into virtual obscurity.
Michael Calpin, 68, is the grandson of able seaman and ninth brother Ernest Calpin, who served on HMS Dreadnought and went on to re-enlist in WW2 before he died in 1957.
The married retired sheet metal worker said: "John was gassed in France in 1916 and was brought back to York but died a few weeks later. All the other brothers survived the war.
"He is the only one to have any physical presence that proves any of the brothers existed really because he was given a war commissioned grave which meant the army paid for his headstone.
"The rest were all buried in paupers graves which are unmarked because they were a poor family living in the slums of York.
"I think that's why they have never been recognised because only one of them died during wartime.
"Their achievement has gone unrecognised; it would just be nice to have a civic-type plaque in honour of the sacrifice they made.
Six brothers signed up for the Army, most with the East and West Yorkshire infantry regiments.
They joined two brothers who were already in military service for British Empire forces at the outbreak of the war.
Arthur Calpin, 24, had served nearly eight years in the Army and was in India when war broke out.
William Calpin, 32, had been serving in Malta. Soon they would reunite with the other seven to fight 'the Hun' on land and at sea.
He was wounded in action, but, like the other brothers, returned to join his family.
An 'Acting Corporal A Calpin' with the East Yorkshire Regiment, mentioned in despatches and listed in the London Gazette in 1917, was almost certainly Arthur.
James Calpin, a 33-year-old former Yorkshire boxing champion, who had previously served in the Boer War, joined the 4th West Yorkshire infantry regiment.
Also in 1917, David, the youngest of the ten, was serving on HMS Ariadne when it was sunk by a German U-Boat.
He was rescued from the water but suffered severe exposure. Although he returned to work for a few years after the war, he died at the age of 32.
Private John Calpin, the eldest brother, was sent back to hospital in Nottingham before he died in York.
He sent a Red Cross postcard to his wife to let her know he had landed safely in England, but died in November 1916 at the age of 39.
