Jana Duggar is a saint. There's no one better when it comes to taking care of her younger brothers and sisters - or nieces and nephews for that matter.
Jessa and Jill Duggar are both married off, but their older siblings John-David and Jana - twins now 25 years old - are still single and ready to mingle.
Josh Duggar, the first kid of the Duggars' 19 Kids and Counting, has 3 and Counting of his own these days (wife Anna is expecting their fourth in 2015)!
