The Duggar clan is taking another step toward growing even more.

Josiah Duggar, the eighth child of reality stars Jim Bob Duggar and Michelle Duggar, has announced that he's going to marry his girlfriend Lauren Swanson. The Duggars rose to fame as stars of 19 Kids and Counting, TLC's reality show about Jim Bob and Michelle's family, which includes their 19 children. The show was originally called 17 Kids and Counting and 18 Kids and Counting as the Duggar family grew during the show's run.

If you're wondering if you missed the news that Josiah, 21, was in a relationship, you probably didn't. Josiah and Lauren, 18, have only been dating since January.

Josiah will be the seventh Duggar child to get hitched, following siblings Josh, Jill, Jessa, Jinger, Joe and Joy-Anna, who collectively have 10 kids with two more on the way.

The Duggars are now stars of the TLC reality show Counting On, which focuses on Jill and Jessa but also features the rest of the Duggars sans Josh, whose child molestation scandal was partly responsible for the cancellation of 19 Kids and Counting.
