Olivia Plath of Welcome To Plathville fame has made some disturbing allegations surrounding a past relationship, presumably from her marriage to Ethan Plath. Olivia and Ethan’s marriage was featured prominently on the TLC reality show about a family of nine kids and their overprotective parents who lived on a family farm in Georgia. Ethan, the eldest son, married Olivia when they were both in their early 20s, as is common in some conservative households.
