PHOTO: 103 year old identical twins die weeks apart

After living most of their lives together, Gleyns Thomas and Florence Davies, reportedly the world's oldest twin sisters, passed away within weeks of each other.

Thomas died on April 23, according to The Telegraph, and her heartbroken sister passed away less than a month later on May 20.

The twins were born in 1911 in Wales.

For most of their lives, they were nearly inseparable, even sharing a room until one of them got married. In their final days, the sisters were living at the Abermill Care Home in Caerphilly, Wales in adjoining rooms.

The sisters were thought to be the oldest living twins in the UK and perhaps even the world, though Guinness World Records say the record for oldest female living twins has been unassigned since July 2014.

They are survived by a total of five children, 12 grandchildren and 19 great-grandchildren. Relatives attributed the sisters' longevity to a simple life enjoyed within a tight-knit family and community.
