When Tom Branson (Allen Leech) drove into our lives during Season 1, we knew the Irishman was going to be trouble. And trouble he was, but in all the right ways.
Despite a rocky courtship, Tom eventually won the heart of Lady Sybil Crawley (Jessica Brown-Findlay), though her family remained lukewarm to the idea — especially when Tom and Sybil moved to Ireland. But they seemed happy enough and soon announced the newlyweds were expecting a wee one of their own.
However, life took an unexpected twist when Tom’s controversial political ties forced him and a heavily pregnant Sybil to flee his home country for the safety of Downton during Season 3. And sadly, things didn’t get any better in England; Sybil, the love of Tom’s life, dies in childbirth leaving the fiery Irish rebel a widower and single father to baby Sybil. One ray of sunshine for Tom: the Crawley family asks him to stay on and help manage the Abbey.
Tom was introduced in Season 1, Episode 4: "May 1913."
