For Enda Bonner, Gaelic games were not a chapter but a thread running from the Donegal team sheet to decades auditing the county board's books and chairing his Dungloe club. Bonner, a former Fianna Fáil senator, county councillor and accountant, died on August 27, 2026, at Letterkenny University Hospital at 76.

Highland Radio published the family notice confirming his death. It named his wife Phyllis, their children Elaine, Elizabeth and Patrick, and four grandchildren, Brooke, Mason, Conal and Elodie. The notice also placed his home in Drumoghill, Manorcunningham, while his public life remained closely identified with his native Dungloe and County Donegal.

Football shaped Bonner's education before it became the structure beneath much of his working life. He attended Gormanston College in County Meath, then studied commerce at University College Galway, where he played in three Sigerson Cup campaigns and captained the team in his final year. He graduated in 1971. His Donegal senior career had begun in late 1969, and he was part of the county panel when Donegal won its first Ulster senior football title in 1972.

A teammate helped turn sport into a profession. Bonner told Donegal Live that he asked 1972 captain Frank McFeely to help him find work after college. McFeely found him an opening with accountant Oliver Freaney in Dublin. Bonner soon assisted with the Donegal GAA accounts and took formal responsibility for that work in 1975. By 2022, the association had lasted more than 47 years.

Accounting gave Bonner another durable institution to build. He became a founding partner of Bonner Gill & Co., which Bonner Gill & Co. says was established in 1984 and later operated from Letterkenny. The firm's own profile joined the strands of his career, identifying him as a commerce graduate, a former senator and a player who had represented Donegal at minor, under-21, junior and senior levels.

Bonner contested Donegal South-West for Fianna Fáil in the 1997 general election. He did not win a Dáil seat, but he was subsequently nominated by the Taoiseach to the 21st Seanad. The Houses of the Oireachtas records his Seanad service from 1997 to 2002. He also represented the Glenties area on Donegal County Council from 1999 to 2009 and again from 2014 to 2019.

As Mayor of Donegal in 2006, Bonner used a rural transport consultation to focus attention on isolation in the Gaeltacht. He pointed to services linking local communities and residents who depended on free travel passes. It was a practical expression of the community politics later captured in Taoiseach Micheál Martin's description of him as a man rooted in both his county and the people he represented.

Bonner kept returning to Dungloe GAA, first as a player and later as chairman, county board delegate and vice-president. His attachment was broad enough to make room for a new code. In 2021, GAA.ie reported that he backed the club's emerging hurling and camogie programme, even as some members of the century-old football club questioned whether it could sustain another sport. By then Dungloe had developed teams from under-eight through senior level, giving younger players a path that had not existed locally before.

Bonner's work remains visible in the Seanad record, the council decisions he helped make, the Letterkenny practice he founded and the GAA accounts he kept across changing generations. In Dungloe, the football club he served also carries the hurling and camogie tradition he supported while it was still new.
