Who Is Lydia Brosnahan?
Lydia Brosnahan is best known publicly for her relationship to actress Rachel Brosnahan, but her background extends beyond the entertainment industry. Before pursuing modeling and communications work, she played college soccer, spent significant minutes as a defender, and scored several important goals.
Her athletic record offers a particularly useful account of her early achievements because it documents her participation, performances, and education independently of her family’s celebrity connections.
In more recent years, Lydia has established a presence in fashion and brand-related work. She has appeared on Arquette Agency’s professional roster, and a 2025 Town & Country profile identified her as a model and public relations coordinator for Weiss Watch Company.
Early Life and Family Background
Lydia was born on August 14, 1998, to Earl and Carol Brosnahan. She grew up in Highland Park, a suburb north of Chicago, alongside her siblings, Rachel and Alec.
Her mother is originally from England, and Miami University’s athletics biography identifies Lydia as a dual citizen of the United States and England.
The Brosnahan family has connections to several creative industries. Rachel pursued acting and eventually became a prominent television performer, while their aunt Kate Spade helped establish one of America’s best-known fashion brands.
Despite these associations, Lydia’s early documented achievements were primarily in sports rather than acting or fashion.
Relationship With Rachel Brosnahan
Rachel Brosnahan, born July 12, 1990, is Lydia’s older sister. She earned widespread acclaim for portraying Miriam “Midge” Maisel in The Marvelous Mrs. Maisel and won a Primetime Emmy Award for the performance.
Rachel has also appeared in House of Cards, The Courier, I’m Your Woman, and Superman.
The sisters have pursued different careers, but their family connection has occasionally become visible at major personal events.
One notable occasion was Lydia’s 2025 wedding, when Rachel served as her matron of honor. The role offered a public example of their family relationship without making Lydia’s own career secondary to her sister’s achievements.
Education and College Soccer Career
Lydia attended Lake Forest Academy in the Chicago area, where she served as a soccer team captain. She also played for Eclipse Select Soccer Club, which qualified for the 2014 Elite Clubs National League national playoffs.
She began her collegiate career at Purdue University in 2016. She appeared in 12 matches, started three, and played 529 minutes. As a defender, she contributed to the team’s defense and recorded 10 shots.
She later transferred to Miami University in Ohio, where her performances became a key part of the women’s soccer program.
Her Breakthrough at Miami University
During the 2017 season, Lydia started 16 matches as a defender and scored twice. Both goals came during a particularly productive period in October.
She scored an overtime winner against Central Michigan on October 13 and another goal against Eastern Michigan two days later, forcing overtime.
These contributions helped her earn Mid-American Conference Defensive Player of the Week honors on October 16, 2017.
In 2018, she appeared in 16 matches, starting 15. She scored two equalizing goals and finished fourth on her team in playing time with 1,416 minutes.
Her performances reflect a college career with regular first-team play and meaningful contributions in competitive matches.
At Miami, Lydia studied strategic communication, a field connected to public relations, media messaging, and brand development. The university’s roster confirms her major, although it does not independently establish her graduation date.
Modeling and Professional Career
After her collegiate athletics career, Lydia built a professional presence in modeling and communications.
She is listed on the official Arquette Agency website, which maintains a portfolio of her modeling photographs and promotional material. The agency’s listing establishes her as a professional model rather than someone with an informal interest in fashion.
Her career has also included work outside modeling.
In September 2025, Town & Country described Lydia as a public relations coordinator for Weiss Watch Company, an American watchmaking business associated with Nashville.
Her professional activities therefore connect several areas: visual presentation, brand communications, marketing-related work, and client-facing representation.
While individual modeling assignments and campaign details are not all publicly documented, her agency representation and reported communications role provide a clear picture of her professional direction.
Lydia Brosnahan and Kate Spade’s Fashion Legacy
Lydia’s late aunt, Kate Spade, was an influential American fashion designer known for her handbags, accessories, and distinctive approach to color and design.
Born Katherine Noel Brosnahan, Spade became internationally recognized through the fashion company she co-founded with Andy Spade.
For Lydia, that connection has remained deeply personal.
During her wedding celebrations, she incorporated several meaningful possessions that had belonged to her aunt. These included a pink Kate Spade Sam handbag, gold bangles, and even hairpins found inside.
She also selected a reception dress inspired by her aunt’s playful yet sophisticated aesthetic.
Rather than simply using a recognizable fashion name, Lydia incorporated objects with direct family significance. The choices made her wedding a personal tribute to Kate Spade’s memory.
Lydia Brosnahan’s Husband, William Sellers
Lydia married William Sellers, an investor and entrepreneur from Nashville, Tennessee, in May 2025.
According to a detailed wedding feature published in 2026, the couple first met in Nashville in 2021 while Lydia was visiting college friends.
They initially traveled between Chicago and Nashville before their relationship grew into a long-term partnership.
William, a former college golfer at the University of Alabama, eventually proposed at Troubadour Golf & Field Club, a location that already held personal significance for the couple.
Their wedding celebrations reflected that same preference for meaningful locations.
Their Nashville Wedding in May 2025
The couple married at Belle Meade Country Club in Nashville, a venue connected to William’s family and to important moments in their relationship.
The celebrations extended over several days and included gatherings with relatives and close friends.
Lydia wore a customized Monique Lhuillier wedding gown for the ceremony and changed into a Danielle Frankel design for the reception.
Her sister Rachel served as matron of honor, while the floral arrangements and wedding cake incorporated peonies in recognition of Kate Spade’s fondness for the flowers.
Town & Country covered the wedding, publishing photographs and details of the celebrations in September 2025.
Personal Life and Public Profile
Unlike her sister Rachel, Lydia has not built a career around film or television. Instead, her public profile is tied to modeling, communications, athletics, and occasional coverage of significant family occasions.
This distinction matters when considering her biography.
Her college soccer statistics show athletic achievement, while her modeling portfolio and documented communications work establish a separate professional identity.
Her wedding brought these aspects of her life together publicly, showing her connections to both the Nashville business community and the Brosnahan family’s fashion heritage.
Conclusion
Lydia Brosnahan’s biography reflects a career and personal journey that is distinct from her family’s prominence in entertainment and fashion. Her accomplishments include competing in NCAA Division I soccer, establishing a modeling portfolio, and working in brand communications.
Her marriage to William Sellers in May 2025 drew additional public attention, particularly through personal tributes to Kate Spade and Rachel Brosnahan’s role as matron of honor.
Although her famous relatives draw public interest to her story, Lydia’s documented athletic background and professional activities provide strong reasons to recognize her on her own merits.
