Now this would be a full-blown Duggar-Caldwell family affair! Some eagle-eyed Duggar fans took notice that Joseph Duggar's wife Kendra Caldwell's younger sister, Lauren, just turned 18 — which makes her old enough to begin courting one of Joe's eligible brothers.

"Jedidiah. He couldn't get Kendra so he'd probably go after her younger sister," one reddit user shared. "Not sure who, but she will be a Duggar because her teeth are nice and straight and she has fundie hair! She is in for sure," another agreed. A third chimed in with, "Lately how all the older guys keep getting with barely-legal girls, I'm gonna say JD." She definitely has some options!

Kendra had quite the controversial entrance into the Duggar family, as she was previously in a courtship with Jedidiah before marrying and getting ready to welcome a child with Joe. Kendra and Lauren grew up in Fayetteville, AR — and were raised in a similarly religious environment as the Duggars. Their father, Paul, is a pastor at the Lighthouse Baptist Church — where the Duggars frequently attend mass. The Caldwell girls also have five other siblings — Micah, Nathan, Timothy, Olivia, and Jesiah — though only Lauren and Kendra have appeared on the TLC reality series.

It would also make sense for Lauren to date a Duggar family member, considering Kendra and Joseph met through their families. Clearly everyone has a good relationship, and we're sure Lauren will be more of a presence in the famous family after her nephew is born on June 18. We think she would make the perfect addition to the Duggar family!
