Michelle and Jim Bob Duggar, 43 and 44
As they continue to change the title of their ever-growing reality-television family, 19 Kids and Counting, stars Michelle and Jim Bob Duggar could actually now call their TLC show, 19 Kids and One Grandkid and Counting. The Arkansas-based family of J’s—Joshua, Jana, John-David, Jill, Jessa, Jinger, Joseph, Josiah, Joy-Anna, Jedidiah, Jeremiah, Jason, James, Justin, Jackson, Johannah, Jennifer, Jordyn-Grace, and Josie—broke form in 2009 when eldest son Josh and his wife Anna welcomed their daughter and picked a new letter, M for Mackynzie Renée. “I can’t believe I’m old enough to be a grandfather,” Jim Bob Duggar told People. “All these kids are keeping us young.” With the birth of their 19th child, Josie, just two months after their first grandchild was born, it seems they’ll stay “young” for some time to come.
