If you're familiar with the lesser-known members of the 19 Kids and Counting clan, then you probably know that Jana Duggar is a fan favorite who always seems to get a raw deal from her own family.

At 25, Jana lives at home with her parents at the so-called "Duggar compound" in Arkansas, where she helps to care for her younger siblings, as well as her nieces and nephews.
