The Duggar family has fascinated fans for years as they've grown bigger and bigger - but could there be even more members we don't know about? "Are there any mystery Duggar grandkids?" a fan asked Jinger Duggar during an Instagram Q&A session on Thursday, February 5. Jinger, who is one of 19 children, jokingly replied, "Ohhh," with the side-eye emoji. "Maybe there are some I don't know about in a family as large as mine?! Haha jk," she added with a laughing, crying-face emoji.
