As the Duggars grow up and get married and the Duggar family tree grows, so do the branches of their in-laws — but we don't see as much of Austin Forsyth and the other spouses' families as we'd like. So we figured it was time to take the initiative to get to know the in-laws on our own. After all, all the new grandchildren are just as much Forsyths and Caldwells as they are Duggars.

Over the past ten years, Jim Bob and Michelle Duggar have seen seven of their kids tie the knot and have welcomed countless new members into their extended family tree. Want to get to know the families of Anna Duggar, Derick Dillard, Ben Seewald, Jeremy Vuolo, Kendra Caldwell, and Lauren Swanson? Check out our gallery of the Duggar family in-laws below.
