In recent months, Josh Duggar's arrest on child pornography charges has been dominating the tabloid headlines -- and with good reason.

The Duggars have been embroiled in one scandal after another for the past six years, and now, it looks as though Jim Bob's house of cards might finally come tumbling down.

Lauren Caldwell is the sister of Joseph Duggar's wife, Kendra Caldwell.

If you're a longtime fan (or critic) of the Duggars and their media empire, then you're probably already familiar with Caldwell clan and their importance to Jim Bob.
