The Emerald Isle has produced some seriously impressive stars – some even from the same family.

These are some of the most famous Irish siblings to know about…

1. The McGregors

Mixed martial arts fighter Conor McGregor is one of the biggest names in the Ultimate Fighting Championship (UFC) – becoming the first person to hold championships in two weight classes simultaneously.

The Dubliner, 35, started his career as a plumber but quickly fell in love with MMA. He hasn’t fought since injuring his leg in 2021, but is set to make his highly anticipated return to UFC later this year.

Conor isn’t the only famous member of his family – his fitness model sister, Erin McGregor, has over 183k followers on Instagram, sharing family, travel and lifestyle shots.

She appeared on the second season of Dancing With The Stars on RTE One, coming fourth with her professional partner Ryan McShane.

2. The Corrs

Family band The Corrs rose to fame in the 1990s with their catchy pop-rock sound. The siblings, Sharon, Jim, Caroline and Andrea Corr from County Louth became synonymous with the Irish music scene.

As well as music, the siblings became well-known for their charity work, and were made honourary MBEs in 2005.

After going on an extended hiatus in 2006 to pursue solo careers, the group released their sixth studio album in 2015 and their seventh in 2017. They came back together to perform in 2022, and are about to embark on a tour throughout Indonesia, the Philippines, Australia and New Zealand.

3. The Mescals

Maynooth-born actor Paul Mescal, 27, became a household name in 2020 when he portrayed Connell in the screen adaptation of Sally Rooney’s novel Normal People.

Paul – who studied at Trinity College Dublin – recently featured in Time magazine’s 100 Next list of influential people on the rise, with fellow Irish actor Colin Farrell praising the “indelibly honest” nature of his acting.

His next big projects include All Of Us Strangers, opposite Andrew Scott, and Foe, with Saoirse Ronan.

His sister Nell Mescal, 20, is an up-an-coming singer-songwriter in the indie music scene, who has been the supporting act for American band Haim, while also playing at festivals this summer including Electric Picnic in County Laois.

4. The Gleesons

The Gleesons are a bonafide acting dynasty, headed up by Irish Film & Television Academy award-winning star of The Banshees Of Inisherin, Brendan Gleeson.

His oldest son, Domnhall, 40, is known for his roles in dystopian romance Never Let Me Go, romantic comedy About Time, and The Revenant alongside Leonardo DiCaprio. He’s appeared in franchises as well, such as the Harry Potter series (as Bill Weasley) and as General Hux in Star Wars films.

Domnhall’s younger brother Brian is also an actor. The 35-year-old recently played Thomas Claffin in Sharon Horgan-developed series Bad Sisters, and appeared as a gangster in the latest season of Top Boy.

5. The O’Connors

Irish equestrian Cian O’Connor, 43, is a big name in the showjumping world.

Having competed in his first Nations Cup for Ireland at age 19, O’Connor represented the country 140 times – including in four World Championships. He won a bronze medal at the London Olympics in 2012, and was part of the gold medal-winning team at the European Championships in 2017.

The Dublin-born showjumper has a well-known sister, Pippa O’Connor. Pippa started her career as a model – she was crowned Miss Kildare and entered the Miss Ireland contest – and went on to build an empire as a blogger, author and entrepreneur, setting up clothing brand Poco.

She published The Pippa Guide: Live Your Best Life in 2019, and is married to TV presenter Brian Ormond.
