It's a sad day for the Sister Wives family.
Robyn Brown's stepfather, Paul Sullivan, has passed away at 80-years-old.
"He was a loving husband and father, dedicated to living life or death on his own terms and with his code of honor," Paul's obituary read on the Hughes Mortuary website per The Sun. "Paul was known for his outstanding principles, integrity, and helping others when needed."
"He expected others to have the same moral compass; if not, he would defiantly (yes defiantly!) let you know." The in memorium continued on to say that Paul "lived, loved, and wanted to be known for those incredible qualities."
"Everyone he came in contact with surely will remember his presence in their life and greatly miss him."
Although Robyn was listed as family in the obituary, fans know very little about her relationship with her stepfather. The tv personality's biological father is named Robert Marck, whom her mother divorced when Robyn was a child.
Her children from her first marriage — Dayton, Aurora, Breanna — as well as her children she shares with reality star Kody Brown — Solomon and Ariella — were also mentioned in the obituary.
As OK! previously reported, throughout season 16 of the hit TLC series, Robyn has struggled watching her sister wives drift further from their relationship with their shared husband, as Kody himself questioned if he even believed in plural marriage anymore.
"When you really start getting honest, you start looking up to the heavens and going, 'Geez, Father. You inspired me to do this. Why is it such a mess now?'" he told host Sukanya Krishnan. "It really has set me on my heels and had me questioning the lifestyle itself. It's a challenge."
"If he doesn't love plural marriage, what does he do?" Robyn asked in the bombshell tell-all. "That's three of us or all of us that he moves on from, and we've seen that in our culture. We have seen that where a man decides he's done living plural marriage and he leaves all of his wives or leaves all but one and he goes and starts a new life."
Kody and Robyn first "spiritually" tied the knot in 2010, and later legally married in 2015 so that the Brown family patriarch could adopt her children from her previous marriage.
