The Duggars have a unique way of choosing middle names for their children. Each child is given a middle name that begins with the same letter as their first name. For example, Josh's middle name is James, Jana's middle name is Marie, and John's middle name is David. This tradition is said to have started with Jim Bob and Michelle Duggar's first child, Josh. They chose the middle name James because it is a biblical name that means "supplanter." They then decided to continue this tradition with their other children.
The Duggars also have a tradition of choosing middle names that have special meaning to their family. For example, Jinger's middle name is Nicole, which is the name of her grandmother. Joy-Anna's middle name is Forsyth, which is her husband's last name. And Josiah's middle name is Matthew, which is the name of his favorite Bible character.
The Duggars believe that their middle name tradition is a way to honor God and to pass on their family values to their children.
