'19 Kids and Counting' matriarch 'Grandma' Mary Duggar dies

The Duggar family is mourning the loss of "Grandma" Mary Duggar.

Jill Duggar Dillard, the fourth of Jim Bob and Michelle Duggar's 19 children, revealed news of the matriarch’s death on Instagram Sunday in a touching tribute.

"My grandma died suddenly today," she captioned a picture of Mary posing with her two great grandchildren, Dillard's sons Israel, 4, and Samuel, 1. "My heart breaks."

Dillard didn't reveal her grandmother's cause of death, but remembered her as a "feisty" and an "amazing woman of God."

"Grandma, you are greatly missed by all who knew you! " Dillard wrote. "I know she was ready to check outta here and get her new body in heaven before the old one started giving her too much trouble!"
