The story of three sets of miracle twins has been revealed, with three sets of parents speaking out about how they had the siblings 15 years apart despite the children being conceived on the same day.
All six children were conceived on the same day in 2002, after Marie and Randy Johnson of Bloomington, Minnesota sought help conceiving a child and donated the other embryos to the National Embryo Donation Center.
The other sets of twins were born years later and to other parents in far-flung states - but that doesn't stop them from seeing each other as one big family.
'These children are true blessings,' Marie Johnson, 53, told the New York Post. 'It doesn't matter that they're different ages and live apart - what matters is that they have the gift of life.'
