The Brudenell family is comprised of six girls and five boys, whose ages range from 68 to 89.
This gives them a combined age of 855 - and an impressive 27 years on the current record holders, nine siblings from Sardinia.

She said: "We're still as close as when we were kids."
If only all world records were as easy to break!
