Guilherme Biro’s Family: Wife, Children, Parents and Siblings

Last Updated on October 2, 2026 by Filepe

Guilherme Biro is a Brazilian professional footballer who plays as a defender for Austin FC in Major League Soccer. His full name is Guilherme da Trindade Dubas, and he was born on May 1, 2000, in Curitiba, Paraná, Brazil. After developing with Coritiba and spending a season at Mirassol, Biro moved to the United States to join Austin FC in 2024.

Biro has spoken several times about how important his family is to him, particularly when explaining his decision to leave Brazil for Major League Soccer. However, he has kept the identities of most of his relatives and his romantic partner away from the public spotlight. What can be reliably established is that he is a father to at least one daughter and announced in April 2026 that another baby was on the way.

Does Guilherme Biro Have a Girlfriend or Wife?

Guilherme Biro (Guilherme da Trindade Dubas), an Austin FC left-back, is married to Letícia Ramos.
Letícia frequently shares the family’s daily life and travels in Texas on social media. The couple describes themselves as very much “homebodies” and has adapted well to the local community, which has a strong Brazilian presence.

Does Guilherme Biro Have Children?

Yes. Guilherme Biro is a father.

Public photography from Austin FC’s 2026 season identifies Biro embracing his daughter after a match against Los Angeles FC at Q2 Stadium on March 21, 2026.

Less than a month later, Biro also announced that his family was expecting another baby.

Guilherme Biro’s Daughter

Biro has at least one daughter. She was publicly identified as his daughter in editorial photography following Austin FC’s MLS match against Los Angeles FC in March 2026.

The footballer has otherwise protected her privacy. Her name, age and other personal information have not been reliably established in the major public sources reviewed.

Because she is a child and Biro has not made her personal details central to his public career, it is appropriate to describe her simply as his daughter unless the family publicly provides additional information.

Guilherme Biro Announced Another Baby in 2026

Another significant family update came on April 4, 2026, when Biro scored for Austin FC against Inter Miami.

His goal was historically significant because it was the first goal scored at Inter Miami’s new stadium. After the match, however, Biro connected the achievement to an even more personal milestone.

He dedicated the goal to a new baby who was on the way and said the child would bring even more happiness to his family.

The announcement indicates that, in addition to the daughter already publicly identified in March 2026, Biro’s family was preparing to welcome another baby.

As of now, I found no sufficiently reliable later report confirming the new baby’s name or whether the birth has since taken place. Those details should therefore not be presented as established facts.

Guilherme Biro’s Parents

The names of Guilherme Biro’s parents have not been reliably disclosed in official Austin FC biographies, established interviews or dependable reporting about the defender.

Biro has repeatedly mentioned his family collectively and has emphasized their support, but he generally does not identify individual relatives.

His family appears to have been closely involved in his journey from youth football in Curitiba through his professional career in Brazil and eventually his move abroad.

Guilherme Biro’s Father

The identity of Guilherme Biro’s father has not been reliably established in the publicly available sources reviewed.

There is no authoritative interview or official biography currently providing his father’s name, profession or background.

For that reason, people sharing the surnames Trindade or Dubas should not automatically be identified as the footballer’s relatives without direct evidence.

Guilherme Biro’s Mother

The name of Guilherme Biro’s mother has likewise not been reliably published.

This is particularly important because there are two Brazilian professional footballers commonly called Guilherme Biro.

The Austin FC defender is Guilherme da Trindade Dubas, born in Curitiba in 2000. Another player, Guilherme Sucigan Mafra Cunha, was born in 2004 and developed at Corinthians.

Brazilian reports that identify a woman named Régia Mafra as the mother of “Guilherme Biro” refer to the younger Corinthians-developed player, not Guilherme da Trindade Dubas of Austin FC.

Therefore, Régia Mafra should not be listed as the mother of the Austin FC defender.

Does Guilherme Biro Have Siblings?

As of now, there is no reliable public information identifying brothers or sisters of Guilherme Biro.

Austin FC’s official biography provides information about his birthplace and professional career but does not mention siblings. Brazilian coverage of his years with Coritiba and Mirassol also provides little dependable information about the structure of his immediate family.

This does not mean that Biro is an only child. It simply means that the identities of any brothers or sisters have not been publicly established through sources reliable enough to present as fact.

Guilherme Biro’s Childhood in Curitiba

Biro was born in Curitiba, Paraná, and spent most of his development years with Coritiba Foot Ball Club.

He entered Coritiba’s youth system at a young age and progressed through several academy categories before eventually reaching the senior squad.

His path to professional football was not guaranteed. Biro later revealed that he came close to being released during his youth career.

The COVID-19 pandemic became an unexpected turning point. While organized training was suspended, Biro continued training intensely by himself at home.

When football activities resumed, he felt physically prepared and received an opportunity to participate in a match involving Coritiba’s youth and professional teams.

That opportunity eventually helped him make the transition into senior football.

Guilherme Biro’s Career at Coritiba

Biro made his professional breakthrough with Coritiba in 2020.

He gradually established himself as a left-sided defender and became an important member of the squad during the following seasons.

In 2021, Biro appeared in 33 of Coritiba’s 38 Série B matches as the club earned promotion back to Brazil’s Série A.

He also formed part of the Coritiba squad that won the 2022 Campeonato Paranaense.

Across his senior spell with the Curitiba club, Biro made more than 70 appearances in all competitions before leaving at the end of 2022.

Guilherme Biro’s Move to Mirassol

Biro joined Mirassol for the 2023 season and enjoyed an important year in Brazil’s Série B.

Playing primarily at left-back, he contributed both defensively and offensively as Mirassol competed near the top end of the table.

His performances attracted attention outside Brazil and eventually helped create the opportunity for him to move to Major League Soccer.

Why Guilherme Biro Moved to Austin With His Family

Family was directly involved in Biro’s decision to accept Austin FC’s offer.

Shortly after moving to Texas in 2024, Biro explained that playing outside Brazil had always been a dream. However, football was not the only reason he accepted the move.

He also said that living in the United States offered an opportunity to provide his family with greater security and a better quality of life.

Biro confirmed that leaving Brazil with his family presented challenges, but he credited their support with making the adjustment easier.

Those comments provide some of the clearest evidence of the importance his family has had throughout his transition from Brazilian football to MLS.

Guilherme Biro’s Life With His Family in Austin

Austin gradually became an important home for Biro and his family.

After completing his first MLS season, Biro agreed to extend his contract with Austin FC. He explained that after spending a year in the city, he had become convinced that Austin was where he wanted to remain.

His family milestones have since become connected with his football career in Texas. His daughter has attended Austin FC matches, while Biro’s 2026 announcement of another baby showed that his family was continuing to grow during his time with the club.

Guilherme Biro’s Historic Goal for His Growing Family

One of the most memorable moments of Biro’s career came against Inter Miami on April 4, 2026.

The match was the first played at Inter Miami’s new stadium, and Biro scored after only a few minutes to become the first player ever to find the net at the venue.

Lionel Messi later scored for Miami, but Biro had already secured his place in the stadium’s history.

Afterward, the Brazilian revealed that the goal had another meaning for him personally. He dedicated it to the new baby his family was expecting.

The announcement connected one of the biggest individual moments of his MLS career with an important development in his family life.
