Double joy for inseparable centenarians.
The twins, who could be the oldest identical twins in Wales, are inseparable.
Their family say they are just as similar today as they were when they were little girls - still wear matching clothes and finishing off each other's sentences.
The pair shared a bed from the day they were born until Marjorie married when she was 21 while Winifred cried herself to sleep because she had never slept alone before. Winfred's son Nolan, 74, said: "They are inseparable - it has been that way since the day they were born and will continue until the day they die. There were times when even their own children didn't know which one was which. I'm sure there were some boyfriends along the way who had the same confusion."
Nolan said the two sisters - who both had four children - believe they are "blessed" by being identical twins.
The sisters were born in 1913 in Pontypool to Sarah Elizabeth Taylor and George Nolan Crump and were joint winners in a beautiful baby competition.
Winifred worked at a boarding school for girls in Pontypool while Marjorie had a milk-round with a horse-drawn cart.
Both married at the age of 21 and went to live with their respective husbands.
But they were reunited when they moved into the same house again while Winifred's husband was away on service.
They each had four children, with nine grandchildren on Winifred's side, and eight on Marjorie's side.
They have 14 greatgrandchildren each, while Winifred has four greatgreat grandchildren and Marjorie has two.
There are thought to be around 10 to 15 twins in the world who have both reached 100 but only a few of them are identical.
