Melissa Mae Carlton became known online for sharing motherhood, photography, faith and everyday family life. But in recent years, her public story has been reshaped by the deaths of two of her daughters, Abigail and Molly, less than two years apart.
Abigail died at 9 in April 2024 after battling sepsis. Then, on Christmas Day 2025, Melissa and her husband, Tom Carlton, lost their younger daughter Molly, who was 5. The second loss initially left the family without a clear explanation. Months later, genetic testing provided a significant medical clue: Molly was diagnosed with PPA2 deficiency, a rare mitochondrial condition associated with sudden cardiac events. (People.com)
The developments have also changed the direction of Carlton’s public work. Alongside documenting parts of her grief, she has increasingly focused on grief support, sudden childhood death awareness and advocacy.
Who Is Melissa Mae Carlton?
Melissa Mae Carlton is a writer, photographer, small-business owner and online creator whose public content has centered on motherhood, family, creativity, faith and grief. In her own introduction to her Substack, Wholehearted, she described herself as a mother, believer, griever, writer, photographer and small-business owner. She also said she runs a faith-based art shop. (Wholehearted)
Her relationship with her husband, Tom Carlton, also predates their family life. According to PEOPLE, the two knew each other as children because their families were friends. Melissa has recalled that Tom was her first real crush and that they went on their first official date when she was 16. They later reconnected after Tom returned from a mission in Scotland and eventually married. (People.com)
Together, Melissa and Tom had four children: Lily, Abigail, Harry and Molly. PEOPLE reported that Lily was born in 2013 and Abigail in 2015, followed later by Harry and Molly. (People.com)
What Happened to Melissa Mae Carlton’s Daughter Abigail?
The first major turning point came in April 2024.
On April 11, Melissa publicly announced that her 9-year-old daughter Abigail had died. At the time, she described Abigail’s death as unexpected and wrote about the family’s grief and faith without initially disclosing a medical cause. She later revealed that Abigail had died from sepsis. (People.com)
That loss became an important part of Melissa’s writing and online presence. In the months that followed, she spoke more openly about the practical reality of grieving while continuing to raise her surviving children. Her Wholehearted Substack, launched in 2025, grew from that period and focuses on grief, motherhood, spirituality, creativity and remembering Abigail. (Wholehearted)
Melissa also said she hoped discussing Abigail’s illness could help other parents recognize the signs of sepsis and better understand what families experience after child loss. (People.com)
What Happened to Melissa Mae Carlton’s Daughter Molly?
About 20 months after Abigail’s death, the Carlton family suffered another loss.
Molly died suddenly on Christmas Day, Dec. 25, 2025, at age 5. Melissa announced the death publicly the following day, writing that Molly and her late sister Abi had been reunited. She also explained that Molly had frequently talked about her older sister. (People.com)
Initially, there was no official diagnosis explaining Molly’s death. Melissa said doctors believed Molly may have had a genetic heart condition and suspected Abigail could have had the same underlying condition. Because Molly had been monitored in hospital before her death, doctors had more information to investigate than they had been able to obtain following Abigail’s sudden illness. (People.com)
That distinction is important when answering the question, “How did Melissa Mae Carlton’s daughter pass away?” Abigail’s death was later identified as sepsis. Molly’s case was initially unexplained, but by April 2026, postmortem genetic testing had identified PPA2 deficiency in Molly. Melissa said her family was “almost 100 percent certain” the same condition had affected Abigail, although the sources reviewed do not establish a separate confirmed genetic diagnosis for Abigail. (People.com)
PPA2 deficiency is a rare inherited mitochondrial disorder. Medical literature has linked the condition to sudden cardiac death and cardiac problems, including cases involving children and adolescents. (PubMed Central (PMC))

Melissa Mae Carlton’s Career and Life Beyond the Tragedy
Before the deaths of her daughters became the central subject of media coverage, Carlton had already developed a creative career around photography, writing, family content and small-business work.
Her online identity combines visual storytelling with faith-based and motherhood-related writing. Her Wholehearted project gives her a longer format for discussing subjects that do not fit easily into social posts, including grief education, spirituality, motherhood and creativity. (Wholehearted)
Her public work has increasingly intersected with advocacy. Following Molly’s death and the later diagnosis, Carlton credited the SUDC Foundation with advocating for postmortem testing. She said she wanted greater awareness of Sudden Unexpected Death in Children and PPA2 so other families might have better access to answers. (People.com)
Melissa Mae Carlton’s story extends beyond the tragedy that brought her wider media attention. She is a photographer, writer, business owner, mother and faith-based creator whose public work changed significantly after losing Abigail in 2024 and Molly in 2025.
The medical picture also evolved over time. Abigail’s death was later attributed to sepsis, while Molly’s sudden death initially remained unexplained before genetic testing identified PPA2 deficiency. That diagnosis has given the family a possible explanation and a new reason to advocate for research and families facing sudden childhood loss. (People.com)
