A couple in Kansas has welcomed twins, making it the fourth generation of twins in their family.
Allen Harkleroad, who has welcomed twins with his wife, is a twin, so are his father and grandfather, News.com.au reported.
Harkleroad was told by the doctors that the odds of his wife Mandy conceiving a fourth consecutive generation of twins were as rare as one in four billion.
However, when his wife finally gave birth to twins, he said that he was pretty shocked but added that it was a mind-blowing thing.
