Welcome To Plathville: The Plath Family Tree Explained

Viewers have gotten to learn a lot more about the Plath family over three seasons of Welcome To Plathville, so it’s interesting to map out how they all fit into the Plath family tree. Kim and Barry Plath are the strict, unconventional parents to nine kids, who were all raised on a large farm in rural Cairo, Georgia. The kids were raised without several things that many other children had access to daily, such as sugar and a television.

Welcome To Plathville season 1 introduced fans to the large Plath family. Alas, the eldest daughter, Hosanna Plath, was absent from Welcome To Plathville in subsequent episodes after moving away from Georgia. Ethan had just gotten married to Olivia Plath, who’s always had a rocky relationship with Kim and Barry on the show. The seasons also followed the self-described “rebel child,” Moriah Plath, who is more interested in makeup and fashion than working on the farm. In turn, Welcome To Plathville has continuously shown the stark contrast between Moriah and obedient Lydia Plath, who’s followed in her parents’ footsteps. Check out all of their family tree details below.

Barry Plath – 54 Years Old

Barry is the Plath patriarch, though many Welcome To Plathville fans believe he is more lenient than his wife Kim and is mostly just following her lead. He was born in 1968, making him 54 years old, and works as a transportation planner.

Kim Plath – 50 Years Old

Kim was born in 1972, and is currently working as a naturopathic “doctor,” a term that has become controversial. The 50-year-old also spends her day homeschooling all of her children and teaching them to play instruments so they could become the Plath Family Band.
