"There is a reason God gives you family," Amy says. "It's for moments like this. We encourage her as much as we can."

Anna was in attendance for Amy's nuptials on Sept. 6, despite all the backlash against her husband following his confession to molesting five young girls as well as his statement admitting he had been "unfaithful" to Anna. An eyewitness told ET that Anna "tried to put a smile on" at the wedding, but that she "looked kind of sad."

"I won't stop trying to get that pig out of our family," he posted on Facebook last month. "I have been thinking of [Anna] and sick to my stomach for her for last few days."

"I don't think Josh will see that this is a big deal and be truly broken till [Anna moving out] happens," he added. "I bet my life on the fact that Josh has not come to true brokenness yet."

According to Daniel, he opened up his home to his sister and her children, but she declined the offer.
