Fans have known Jackson and Johannah Duggar since the moment they were born, Jackson in 2004 and Johannah in 2005. When the Duggars first appeared on TV, in 14 Children and Pregnant Again, Michelle was expecting Jackson. His birth was featured in that special, and Johannah made her debut in the following special, Raising 16 Children.
Now almost 20 years later, this brother-sister duo has reached an exciting milestone. They both just graduated from high school! As they have done for their other children, Jim Bob and Michelle Duggar celebrated Jackson and Johannah with a ceremony, a party, and senior pictures. Photos can be found on the Duggars' website. Jackson turned 19 in May, and Johannah will be 18 in October.
