Josiah Duggar of 19 Kids and Counting announced yesterday that he is courting a young lady, and now, it seems, Jill and Jessa Duggar’s little brother joined Instagram the day before the big announcement.

Now that his big sisters are married, it looks like Josiah — Si as he his lovingly known by family and friends — is next in line to go a-courtin’.

On Sunday, Josiah Duggar joined Instagram and on Monday he announced that the is dating — oh sorry, courting — 17-year-old Marjorie Jackson.

His first ever post on Instagram featured a photo of a bumper sticker that reads, “Evil thrives — when good people do nothing.” He added his debut hashtags, “#bumpersticker #dogood.”

His second was the big news about his young lady.

“I’m so excited to announce that I’m courting Marjorie Jackson! #19Kids @peoplemag @duggarfam,” he wrote.

Sister Jessa Duggar, 22, also announced her brother’s good news on her own Instagram page.

“Another Duggar is courting! Congrats to my bro Si and his girlfriend Marjorie!” Jessa captioned a photo of the young couple.

This could be serious, folks. Courtship is a whole lot different from dating. Young people in a courtship are getting to know one another with one, single purpose — marriage. The young loves will not ever meet with chaperones present. They will be allowed to hug, but, like Josiah Duggar’s sisters, there is no kissing until the wedding day.

“It’s been going very well,” Josiah told E!. “I met Marjorie a few years ago, when I was taking Spanish lessons at her house and I was very impressed with the way she was with her siblings and her love for the Lord.”
