Mark Tomlinson is best known as the father of Lottie Tomlinson and as an important father figure in the wider Tomlinson family. He has spent much of his life in Doncaster, where he was born, raised and later built his own working life. While his connection with Louis Tomlinson and Lottie Tomlinson has brought public attention, Mark has maintained his own identity through writing, consulting, social media and family life.
His personal story includes marriage, fatherhood, work and a long connection with one of Britain’s most recognisable celebrity families. He was previously married to Johannah Deakin, with whom he had four daughters, including Lottie Tomlinson. He later married Sallie Tomlinson, who continues to refer to him publicly as her husband. His own social media presence also shows a strong interest in family, writing, personal reflection and everyday life.
Who Is Mark Tomlinson?
Mark Tomlinson is a British writer and consultant from Doncaster, England. He was born on 13 August 1969 and turned 57 years old on 13 August 2026. His social media accounts show a long-standing connection with Doncaster, which is both his hometown and current city.
He attended Hall Cross Comprehensive School and later built a career that has included consultancy work. His Facebook details identify him as a consultant at UK & The World from 2012 onwards. His Instagram biography describes him as a writer and also mentions podcast work, showing that his interests now extend beyond traditional employment.
Although Mark is not a mainstream television personality, his connection to the Tomlinson family has made him familiar to many fans of Louis Tomlinson and Lottie Tomlinson. Over the years, he has shared family moments, birthdays, personal thoughts and messages about those closest to him.
Mark Tomlinson Age and Birthday
Mark Tomlinson was born on 13 August 1969. This makes him 57 years old as of August 2026. His birthday is supported by his Facebook details, while his wife Sallie also publicly celebrated his birthday on 13 August. Sallie shared a warm birthday message on Instagram in which she called him her “lovely husband” and tagged his account directly. This gives a clear connection between his identity, his birthday and his marriage.
His date of birth also fits with the life stage shown across his family history. By the time his children were growing up, Mark had already established himself in Doncaster and was involved in family life that later became well known because of Louis Tomlinson’s rise to fame.
Mark Tomlinson Wife Sallie Tomlinson
Mark Tomlinson is currently married to Sallie Tomlinson. Their relationship is openly acknowledged on social media, and Sallie has directly referred to Mark as her husband. The couple married on 31 March 2016. Mark had posted before the wedding about getting married the following morning, and the date has remained associated with their marriage since then.
Sallie’s recent birthday message for Mark gives strong first-hand confirmation that they remain married. In the post, she wished him a happy birthday, called him her husband and expressed her love for him. Comments beneath the post also referred to Mark as a husband, father and grandfather.
Mark Tomlinson and Sallie Tomlinson
Mark and Sallie have built a private family life while still sharing selected moments online. Their social media activity is warm and family-focused, with birthday wishes, personal comments and celebrations appearing from time to time.
Sallie’s account has helped confirm several details about Mark’s current personal life, especially his marital status. This is useful because Mark’s name can sometimes be confused with other British men with the same name. Their marriage is an important part of Mark’s present-day life, and Sallie remains clearly connected with him across both family and social media circles.
Mark Tomlinson Ex-Wife Johannah Deakin
Before marrying Sallie, Mark Tomlinson was married to Johannah Deakin. She was also known as Johannah Poulston during parts of her earlier life. Mark and Johannah had four daughters together: Charlotte Elizabeth “Lottie” Tomlinson, Félicité Tomlinson, Phoebe Tomlinson and Daisy Tomlinson. Their marriage placed Mark at the centre of the family that later became widely recognised because of Louis Tomlinson.
Johannah later had further children after her relationship with Mark ended. She remained a major figure in the lives of her children until her death from leukaemia in December 2016.
Mark Tomlinson and Johannah Deakin
Mark and Johannah shared a major part of their adult lives through marriage and raising children. Their daughters remained connected to both parents, while Mark also took on a fatherly role in Louis Tomlinson’s childhood.
Johannah’s death had a huge impact on the wider family. She was only 43 when she died, and several of her children were still very young adults or teenagers.
Mark’s own social media history shows that family remained important to him even after changes in his personal relationships.
Mark Tomlinson Children
Mark Tomlinson is the father of four daughters with Johannah Deakin. They are Lottie Tomlinson, Félicité Tomlinson, Phoebe Tomlinson and Daisy Tomlinson.
Lottie, whose full name is Charlotte Elizabeth Tomlinson, was born on 4 August 1998. She later became a beauty entrepreneur, digital creator, author and make-up artist. She is now one of the most famous members of the family in her own right.
Félicité Tomlinson was born in 2000 and died in March 2019 at the age of 18. Her death was another major tragedy for the family following Johannah’s death only a few years earlier.
Phoebe and Daisy Tomlinson are twins. Both have built social media followings and remain part of the wider Tomlinson family presence online.
Mark Tomlinson and Lottie Tomlinson
Mark Tomlinson is Lottie Tomlinson’s biological father. This relationship is supported strongly through family references and Mark’s own social media activity.
He has publicly referred to Lottie as his daughter, and she remains one of the most visible members of his immediate family. Lottie’s full legal name, Charlotte Elizabeth Tomlinson, also connects directly with the family name.
Lottie has built a successful career in beauty and business through projects such as Tanologist, social media work and publishing. While her older half-brother Louis became famous through music, Lottie developed her own identity in a very different field.
Mark has remained part of her family story through the years.
Mark Tomlinson and Louis Tomlinson
Mark Tomlinson is not Louis Tomlinson’s biological father, but he played a major fatherly role in Louis’s childhood.
Louis was born Louis Troy Austin. His biological father is Troy Austin. Mark later became his stepfather after marrying Johannah, and Louis took the Tomlinson surname.
This is one of the most important facts to explain correctly. Mark should not be described as Louis’s biological father, but his role in raising him was significant.
Mark Tomlinson as a Father Figure
Mark has spoken strongly about the role he played in Louis’s life. In an older social media post, he described himself as Louis’s dad and said he had been there throughout his life.
That wording reflects the emotional and family role Mark held, even though the biological relationship is different.
For many years, the Tomlinson surname became strongly associated with Louis’s public identity. Mark therefore remains an important figure in understanding Louis’s childhood and family background.

Mark Tomlinson as a Writer

The podcast reference in his Instagram biography may also point to a growing interest in spoken content or discussion-based media.
