Who Is Lydia Brosnahan?
Lydia Brosnahan Sellers is an American model and public relations professional. Born on 14 August 1998, she is 28 years old as of October 2026. She grew up in Highland Park, Illinois, and comes from a family with strong connections to entertainment and fashion.
Although Rachel Brosnahan’s success made the family name familiar to television audiences, Lydia has worked in different industries. Her background includes university football, fashion marketing and professional modelling. She has worked with Frances Valentine and Weiss Watch Company and is represented by Arquette Agency.
Early Life and Family Background
Lydia was raised in Highland Park, Illinois, a suburb of Chicago. Her parents are Earl and Carol Brosnahan, and she has two older siblings, Rachel and Alec. Her mother is originally from England, giving Lydia family connections to both Britain and America. Her university athletics records also confirm that she holds dual British and American citizenship.
Sport was an important part of her childhood. She attended Lake Forest Academy, where she played football and eventually became captain of the school team. Outside school, she competed for Eclipse Select Soccer Club, developing her skills against other talented young players. Her commitment to football helped her earn opportunities at university, where she continued playing at a competitive level.
Lydia Brosnahan’s Education and Football Career
Before entering the fashion industry, Lydia spent several years playing college football as a defender. She began at Purdue University in 2016, making 12 appearances during her first season. She started three matches and played more than 500 minutes, gaining experience against strong university teams.
In 2017, Lydia transferred to Miami University in Ohio, where she became a regular member of the women’s football team. She started 16 matches that season and scored two goals. One of her most memorable performances came against Central Michigan, when she scored the winning goal in extra time. Her strong defensive performances helped her earn the Mid-American Conference Defensive Player of the Week award.
Her progress continued in 2018. Lydia appeared in 16 matches, started 15 and scored twice. She also played the full match on 12 occasions, showing how much the team depended on her. Alongside football, she studied strategic communication, a subject that later became useful in her professional career.
How Lydia Brosnahan Entered the Fashion Industry
After university, Lydia moved towards marketing and public relations. One of her important professional roles was with Frances Valentine, the fashion company co-founded by Kate Spade and Elyce Arons. She worked there as a community marketing and public relations manager from October 2021 until March 2024.
The role gave her experience in a creative business closely connected to her family. Frances Valentine produces clothing, handbags and accessories, with a style that reflects Kate Spade’s love of colour and playful design. Lydia’s work placed her inside the fashion industry, where she could develop practical experience in brand communication.
In November 2024, she joined Weiss Watch Company as a marketing and public relations coordinator. The American watchmaker was a different kind of business, but the position allowed her to continue working in communications. Her career history shows an interest in brands, fashion and the way companies connect with customers.
Her Modelling Career with Arquette Agency
Fashion marketing is not Lydia’s only professional interest. She has also worked as a model and is represented by Arquette Agency. Her agency profile includes fashion photographs, professional portraits and a digital modelling portfolio.
Her modelling work is separate from Rachel’s acting career, although both sisters have experience working in front of a camera. Lydia has focused on fashion-related opportunities rather than television or film. Information about individual modelling campaigns remains limited, but her agency representation confirms her involvement in the industry.
Her Relationship with Rachel Brosnahan
Rachel Brosnahan became internationally recognised through her leading role in The Marvelous Mrs. Maisel. Her performance as Miriam Maisel earned her an Emmy Award and several other honours. In 2025, she appeared as Lois Lane in the film Superman, bringing her work to an even wider audience.
Lydia and Rachel have chosen different careers, but they share an important family bond. Rachel was closely involved in Lydia’s wedding preparations and served as her matron of honour. She wore a lavender dress during the ceremony and stood beside her younger sister as the couple exchanged vows. The occasion was a rare public glimpse of the sisters celebrating together.
Lydia’s Connection with Kate Spade
Lydia’s late aunt, Kate Spade, was an American fashion designer whose handbags became popular around the world. She helped establish the Kate Spade brand and later co-founded Frances Valentine. Kate died in June 2018, but her work continues to hold a special place in fashion.
For Lydia, Kate was also a close family connection. Her memories of her aunt became particularly visible during her wedding celebrations. Several personal belongings that Kate once owned were included in the occasion, allowing Lydia to remember her in a simple but meaningful way.
How Lydia Brosnahan Met William Sellers
Lydia met William Sellers, an investor and entrepreneur from Nashville, in 2021. She was visiting college friends when they crossed paths at the Dream Hotel in Nashville. What began as an unexpected meeting developed into a relationship, even though they were living in different cities.
The couple spent part of their relationship travelling between Chicago and Nashville. William, who previously played university golf at the University of Alabama, shared Lydia’s interest in sport. When he decided to propose, he chose Troubadour Golf & Field Club, a place they already enjoyed visiting.
Following dinner, William asked Lydia to marry him beside an outdoor fireplace. Eight of their close friends were waiting nearby to celebrate. The proposal was personal rather than public, and the couple later carried that same approach into their wedding plans.
Lydia Brosnahan and William Sellers’ Nashville Wedding
Lydia and William married on 24 May 2025, at Belle Meade Country Club in Nashville, Tennessee. The venue was familiar to William’s family, who had been connected to the club for many years. The couple had also celebrated important moments there during their relationship.
Their wedding festivities took place over several days. The celebrations included a welcome gathering, a golf outing at Troubadour Golf & Field Club and a rehearsal dinner at Drusie & Darr, a restaurant inside Nashville’s Hermitage Hotel.
For the ceremony, Lydia chose a customised Monique Lhuillier Vittoria gown from the designer’s Spring 2025 collection. She later changed into a Danielle Frankel dress for the reception. The wedding featured colourful flowers, family photographs, music and a cake decorated with handmade sugar peonies.
The Wedding Tributes to Kate Spade
Some of the most personal details of Lydia’s wedding were connected to her late aunt. At the rehearsal dinner, she carried a rare pink Kate Spade Sam handbag that had belonged to Kate. She also wore two gold bangles from her aunt’s jewellery collection.
While looking inside the handbag, Lydia discovered two hairpins that Kate had left behind. She decided to include them in her wedding hairstyle. It was a small detail, but one that allowed her aunt’s memory to become part of the ceremony.
Peonies were another important part of the celebration because they were among Kate’s favourite flowers. Lydia included them in her bouquet, wedding decorations and cake design. She also chose her reception dress with Kate’s personal fashion style in mind, bringing another family connection into the evening.
Married Life and Career Today
Following their wedding, Lydia and William spent a few days at The Breakers in Palm Beach, where they had previously enjoyed time together. They later travelled to Italy’s Amalfi Coast for a longer honeymoon with friends.
Although photographs and details of their wedding appeared in lifestyle publications, the couple have shared relatively little about their everyday married life. There is no reliable public confirmation that they have children. Lydia’s publicly documented professional background remains centred on modelling, marketing and public relations.
Conclusion
Lydia Brosnahan has followed an unusual career path, moving from competitive college football into fashion, modelling and brand communications. Her family connections have brought attention to her name, but her sporting achievements and professional experience are important parts of her story.
Her marriage to William Sellers marked a new chapter in May 2025. With her sister Rachel beside her and several touching reminders of Kate Spade, the wedding celebrated both her relationship and the family memories she continues to value.
