McAvoy's Secret Second Son & Estranged Brother
2 Apr
Summary
- James McAvoy secretly welcomed a second child, a son.
- His estranged brother Donald is serving a prison sentence.
- McAvoy's father died before reconciliation was achieved.

James McAvoy has revealed the recent birth of his second son, a surprise to many fans. He noted that fatherhood at 42 is easier than his first experience, attributing this to less worry and a more philosophical outlook. This personal news stands in sharp contrast to his deeply fractured family relationships.
McAvoy's younger brother, Donald, is reportedly serving a significant prison sentence. The half-brothers are believed to have no contact, their lives having taken vastly different trajectories. Donald is currently facing a potential life sentence after a violent incident in HMP Saughton.
Their father, James Senior, a bus driver-turned-builder, died years ago without reconciling with James. James was estranged from his father from the age of 12, following his parents' separation when he was seven. He was raised by his maternal grandparents in Glasgow.
Donald has extensive prior convictions and recently admitted to assaulting a fellow inmate with a bladed object in October 2025. He is currently being assessed for a lifelong restriction order. The court case is scheduled for June 9, 2026. He is also awaiting potential release in March 2025 but received additional time for contraband found in his cell.
Despite his father's attempts at reconciliation, including a public plea in 2006, James did not reconnect. His father was last reported in court on drug dealing charges in 2013 with Donald. Donald has since inherited a "sizeable legacy" from his father's estate.
