How old is Too Good To Be True star Allen Leech?

Allen Leech was born on May 18, 1981 in Killiney, County Dublin. At the time of writing, he is 42 years old.

The Irishman in Downton Abbey!

Allen Leech is best known for portraying Tom Branson on the hit ITV drama Downton Abbey (2010-2015).

Radical socialist Tom was a chauffeur for the aristocratic Crawley family, who opposed much of what the family stood for. Nonetheless, he fell for the youngest Crawley daughter Sybil (Jessica Brown Findlay), who shared his political views.

Tom and Sybil married in Ireland, but tragically Sybil died while giving birth to the couple’s daughter, Sybbie, in series 3. Tom’s later storylines included his grief at the passing of his wife, as well as his perceived failure to fit in as an adopted member of the Crawley family. Tom moved to Boston in series 5, before returning home to Downton Abbey in series 6. In the films, he found love a second time, with maid Lucy (Tuppence Middleton).

Allen appeared as Tom in all seasons of Downton Abbey, as well as the two feature films in 2019 and 2022.

Prior to Downton, Allen also had recurring roles in Love Is the Drug (2004), Legend (2006) and HBO epic Rome (2007).

Most recently, Allen starred in Irish drama The Vanishing Triangle. While the series has already aired in the US, it should air in the UK on Acorn TV soon.

Is Allen leech related to Niall Horan?

Despite an uncanny resemblance between Allen Leech and the One Direction musician Niall Horan, the two are not actually related.

The pair have, however, joked multiple times about their likeness. Notably, Allen told Watch What Happens Live that Niall was his son. He added: “I had him really young. I had the choice to give him to the circus or a boy band, I chose a boy band. He’s done much better there because his backflips are terrible.”

Allen has also joked that Niall Horan could play a younger version of Tom Branson in a Downton Abbey prequel film, while Niall has told fans he’d like Allen to portray him in a biopic about his life.

The pair’s friends are even in on the joke. In 2023, American TV personality Blake Shelton wished Niall a Happy Birthday on X with a picture of Allen attached.
