Twin Sisters, Twin boys delivered the same day

On 2004, twenty-one-year-old twins Ashlee Spinks and Andrea Springer both delivered twin boys by Caesarean section at Northside Hospital (Georgia, USA) at the same day. 

The mothers – who did not use fertility drugs to conceive - were 6 months pregnant when they discovered they were both carrying twin boys and were both due on the very same day. 

This “one in a million” coincidence is attributed mainly to the fact that not only do Ashlee and Andrea have an obvious history of twins in their family, but both their husbands’ families also have a history of twins.
