Jim Bob Duggar, star of the reality show "19 Kids and Counting," is known for his large family, having fathered nineteen children with his wife Michelle. The couple had two more children after the series began airing, prompting the show to be renamed twice. Tragically, their 20th child, Jubilee Shalom, was miscarried. Jim Bob's oldest son, Josh Duggar, has fathered six children himself, continuing the family's tradition of large families.
