“A Florida woman was doubly surprised last year to deliver two sets of twins and to learn they run in her family.
Alexzandria Wolliston gave birth to her first set of twin boys, Mark and Malakhi, in March, and her second set, Kaylen and Kayleb, in December, all of whom she said were conceived naturally.
Wolliston, 25, said that prior to giving birth to Mark and Malakhi, she was unaware twins ran in both sides of her family.”
