The Bartletts were born to Victorian parents in the early 1900s before the common use of electric light or gas cookers.
Together they have seen off 19 Prime Ministers, five Monarchs and two World Wars.
Today Kathleen, 102, Gladys, 100, Lillian, 94, Leonard, 92, and Courtney, 86, are still around to witness the online revolution and birth of 3D television.
The quintet currently have a combined age of 474 years are now preparing to enter the record books as the world's oldest living siblings.
Their family put the achievement down to decades of hard work.
Gladys' daughter Lucille Ademante, 68, of Bristol, said: 'They are truly remarkable.
'They have all been pretty active for most of their lives but I would not say their lives have been easy.
'Our whole family is really proud of them - everyone thinks they are fantastic.' Oldest daughter Kathleen Clark was born in 1908 - the year Herbert Asquith took office in Downing Street - and went out to work as a maid the age of 12.
She retired after years of factory work in her 70s and celebrated her 100th birthday two years ago with family at her nursing home in Weston-super-Mare, Somerset.
