She is the sister of Joshua Duggar, Jana Duggar, John-David Duggar, Jill Dillard, Jessa Seewald, Jinger Vuolo, Joseph Duggar, Josiah Duggar, Jedidiah Duggar, Jeremiah Duggar, Jason Duggar, James Duggar, Justin Duggar, Jackson Duggar, Johannah Duggar, Jennifer Duggar, Jordyn-Grace Duggar, and Josie Duggar.
Being born in the midst of eight boys, Joy-Anna was said to be a tomboy growing up. She was more likely to be found playing outside and roughhousing with her brothers, rather than doing the more typically feminine activities her parents encouraged. She was especially close to her brother Josiah as a child.
Along with her siblings, Joy-Anna was homeschooled growing up. She and her siblings were raised as active participants of Bill Gothard's Institute in Basic Life Principles, and regularly attended the yearly Advanced Training Institute conferences in Big Sandy, Texas. She took the test to get her GED in 2016, at eighteen years old, alongside her younger brothers Jedidiah and Jeremiah. Her family had a graduation party to celebrate this event.
Like most children, Joy-Anna was assigned chores growing up, which the family called "jurisdictions". As of 2004, Joy-Anna's jurisdiction was laundry, alongside her sister Jill. As of 2011, Joy-Anna's jurisdiction was cleaning the girl's room. It is likely that Joy-Anna was relieved of her jurisdictions when she began her courtship, as her older sisters had been when beginning their courtships.
By 2001, Joy-Anna's parents had implemented a buddy system, where each older child was paired with a younger child to take care of. Typical tasks for an older buddy included dressing, bathing, and feeding their younger buddies. From the earliest implementations of this system, Joy-Anna was shown as the younger buddy of her sister Jill. By 2009, the family had switched from individual buddies to buddy teams, with each team being led by one of the oldest four daughters. Joy-Anna remained with her sister Jill in this system, and their team also consisted of younger siblings James and Jennifer. This team has been shown to still maintain a strong bond today. When Jill got married in 2014, Joy-Anna took over as the head of the buddy team.
Joy-Anna took piano lessons as a child, but it is unknown if these lessons were from the family's first piano teacher, Ruth Anita Anderson, or if her older siblings had taken over with the lessons by the time she was old enough to learn. Joy-Anna also took violin lessons as a child.
In 2006, as featured on one of the TV specials, Joy-Anna and her family moved into a new home in Springdale, Arkansas. The family made a point of doing much of the work on the house themselves, seeing it as a learning opportunity for their children. In this house, Joy-Anna was given a dormitory-style room with her sisters.
In late 2009, after her sister Josie was born premature, Joy-Anna moved with her family into the Cornish House in Little Rock, Arkansas, to be closer to the Arkansas Children's Hospital. Once Josie was healthy enough to leave the Neonatal Intensive Care Unit (NICU), Joy-Anna and her family moved back home.
In 2010, Joy-Anna was an extra in the film Courageous, which was released on September 30, 2011. Although the entire family was on set, Joy-Anna was one of the only family members to make it into the film's final cut. She is seen in the film attending a young girl's funeral. When the scene was filmed, her family expressed surprise that Joy-Anna was able to cry real tears for a fictional death.
Thanks to the reality show, Joy-Anna was able to take a number of vacations as a child and teenager. Notable vacation locations include: Disneyland, New York City, Niagara Falls, Scotland, Ireland, London, Israel, China, and Japan.
On November 15, 2016, Joy-Anna announced that she was in a courtship with long-time friend Austin Forsyth. The couple said that they had been friends for almost fifteen years, although Joy-Anna later said that she didn't remember him as a child. Austin took Joy-Anna out to a special spot at Pedestal Rocks in Ozark National Forest to ask her to court him, and she enthusiastically said yes. Their courtship proposal is featured on the Counting On episode "A Honeymoon & a Courtship".
On March 3, 2017, the couple announced that they were engaged. The couple got engaged on March 2, 2017, in the Ozark National Forest at Fort Rock. Austin took Joy-Anna, along with her sisters Johannah and Jennifer, horseback riding, before leading her to a cliffside where he proposed to her. He then took her to a clearing where he and his friend, Aaron Patton, had set up a table to eat a special meal that he had prepared for them. Joy-Anna said that she didn't expect a proposal at that moment because she didn't see any TV cameras there to film, but they were hiding in nearby trees and bushes to help make the moment more special. Their engagement is featured on the Counting On episode "Joy Gets Engaged".
On May 26, 2017, Joy-Anna married Austin Martyn Forsyth at Cross Church in Rogers, Arkansas. The wedding had around 1,000 guests. The couple shared their first kiss at the altar.

Her bridesmaids were her sisters Jana, Jessa, Jinger, Johannah, and Jennifer, her sister-in-law Anna, Austin's sister Meagan, and her friends Kendra Caldwell, Carlin Bates, Sierra Dominguez, and Heidi Query. The flower girl was Austin's half-niece Allove. Austin's best man was his brother-in-law Bobby Ballinger.

"We chose Switzerland because we knew that it was very beautiful," Joy explained in an interview. "We had seen a lot of pictures and Austin has really wanted to come here for awhile."
