Carlin Brianne Bates was born on April 11, 1998, to Gil Bates and Kelly Jo Callaham. She was the couple's ninth child, and they went on to have ten more children after her.
Carlin was homeschooled growing up. She and her siblings were raised as active participants of Bill Gothard's Institute in Basic Life Principles. While in high school, she took dual enrollment classes at a local college (likely Crown College of the Bible's Early Advantage program).
She and her brother Trace graduated from high school together in 2016. They held a graduation party at Mount Moriah Camp, which was planned by Carlin and open to the public. Erin, Lawson, Tori, and Carlin sang the song "All Along" by Rebecca J. Peck and Mark Lanier at the party. Many of the older Bates kids and friends performed skits at the party as well. At the party, Carlin's brother Nathan asked her who she aspired to be, and her answer was her father: "He’s always been faithful in the little things. He’s steady in the Lord. Whatever he does, he doesn’t lose his cool."
In the season six finale of Bringing Up Bates that aired on September 14, 2017, Gil gave Evan and Carlin the green light to enter a courtship; the episode did not feature the beginning of a courtship. Commercials for the season seven premiere of Bringing Up Bates advertised that the episode would feature a courtship proposal. This was the first public information that the couple was officially courting. On the January 4, 2018, UpTV released an official courtship announcement a few hours before the season premiere. In that night's episode, Evan took Carlin on a scavenger hunt around east Tennessee, ending at the Norris Dam. Once at the dam, Evan sang a song he had written for Carlin and presented her with a bracelet, and she agreed to enter a courtship with him. "Just looking back and seeing all the thought and all the work that went into what Evan did for me and making this day super special, I was overwhelmed with the love he showed me and all the participation of everybody," Carlin said of the courtship proposal.
On September 24, 2018, Carlin announced that she is engaged to Evan Stewart. He proposed at Portland Head Lighthouse in Portland, Maine, after spending a romantic day exploring Portland together.
Carlin married Evan Stewart on May 25, 2019, at Castleton Farms in Loudon, TN. She had two matrons of honor, her sister Erin Paine and sister-in-law Whitney Bates. Her bridesmaids were her sisters Michaela Keilen, Alyssa Webster, Tori Smith, Josie Balka, and Katie Bates, future sisters-in-law Ashley Sparkman, Brittany Randolph, and Maegan and Kailyn Stewart, and friend Joy Forsyth. Her sisters Addallee and Ellie Bates were junior bridesmaids, and her sister Callie Bates and future nieces Braelyn and Bella Randolph were flower girls. Her brothers Zach, Lawson, Nathan, Trace, and Jeb Bates were among the groom's party. The wedding was officiated by Frank Gagliano and her father Gil Bates.
Carlin and Evan's honeymoon location is currently unknown, but given the photo of their passports that Carlin posted the day after the wedding it is likely somewhere outside of the United States.
