If recent rumors are to be believed, there is a family feud brewing in the Duggar family. It seems that there have been claims swirling for a while now that Jinger Duggar Vuolo and her husband, Jeremy Vuolo have been having issues with Jill Duggar Dillard and her husband Derick Dillard. Fans have noticed that Neither Jill nor Derick follow Jinger or Jeremy on social media, which makes some question the narrative of the super-close older sisters in the Duggar Family. No one can quite pinpoint what is going on behind the scenes, as the Duggars like to portray a picture-perfect family, but there are some theories floating around.

What caused the rift between the sisters?

If there is, indeed, a rift between the girls, it is unlikely either will ever speak up and share it since the Duggars are all about presenting a picture-perfect family. However, some fans have ideas about what's gone on between them. Jinger Duggar Vuolo and her husband Jeremy have been using their first year of marriage to get to know one another and travel, without kids. This is pretty rare for a Duggar, as the family is known for making a pregnancy announcement just a few months after the wedding night. Some suspect Jill is jealous that her younger sister is gallivanting around child-free and living life to the fullest.

Another popular theory is that Jeremy Vuolo, who is a pastor at a church in Laredo, Texas, feels that Jill Duggar Dillard and Derick Dillard are not qualified missionaries.

The pair, who have never had their work sanctioned by a church, have relied on donations of fans and supporters and have never completed any kind of schooling or training to be missionaries. Jeremy recently preached against those who are not affiliated with a church, claiming they are "unqualified, uncalled, unconfirmed, unsent zealots" and that they do more harm than good with their work.

Michelle Duggar confirms the argument?

Some believe Michelle Duggar may have confirmed that the girls are feuding in a recent quote she posted on the family's blog. The family has never shared discord or discontent amongst their ranks, so some think this is a cryptic way for Michelle to acknowledge that her daughters are not getting along.

"Comparing ourselves to others, envy, and jealousy all lead down a road to bitterness. Bitterness can cause us to be harsh and to treat others unfairly — sometimes unknowingly! One thing we must do as Christians is to pray that bitterness finds no place in our hearts. Let's choose joy!" Michelle wrote.

While this doesn't confirm anything, it does allude to the fact that things aren't as perfect as they seem in the Duggar house.
