The entire Roloff family may not always appear on Little People, Big World these days, but that doesn't mean the crew doesn't get together when the TLC cameras are off.

Family patriarch Matt Roloff shared a photo on Instagram on Sunday featuring his daughter Molly and youngest son Jacob, who no longer star on the reality show. The duo made a rare appearance at a family gathering over the weekend in honor of grandfather Ron's special birthday milestone.

"The best weekend celebrating my dads 80th," Matt captioned a photo of the group wearing matching blue shirts that read "80 Years Young and Going Strong. "Can the diehard Roloff fans identify everyone In the clan? Hint: my sister Ruth has 3 daughters one married. My brother Sam has 3 kids ... Audrey and Ember are there in spirit. Try to guess who’s who."

Amy Roloff, Matt's ex-wife and fellow star of Little People, Big World, was noticeably missing. The couple divorced in 2016, and Matt is now dating a woman named Caryn Chandler, who is pictured in the first photo above.

Molly was one of the relatives to travel the farthest for the reunion. She currently lives in Spokane, Washington, with her husband Joel Silvius, which is one of the main reasons we barely see her on Little People, Big World. Most of the other family members live closer to Roloff Farms in Hillsboro, Oregon.

Jacob can also be seen standing next to his fiancée, Isabel Rock, toward the far right. The pair aren't on TLC since Jacob decided in 2016 that he would no longer partake in the show due to issues with production. In January, he proposed to Isabel and the couple plans to marry next year, which means the Roloff clan will only continue to grow in the years to come.
