Jessa, 21, is set to marry
fiancé Ben Seewald, 19, on November 1 and all signs point to her and her new hubby following her parents' tradition when it comes to having babies. According to the Duggar family web site
, family matriarch and patriarch Michelle and Jim Bob "asked God to bless them with as many children
as He saw fit in His timing." Jessa's oldest brother, Josh, already has three kids with his wife, Anna, while sister Jill is currently expecting her first baby
in March, having gotten pregnant shortly after her June wedding
to Derek Dillard.
