[6] A teenage Manus McFadden arranged a meeting at Foxhall of Glenswillyites who were interested in forming a team, with John Mc Ginley, Roger McDaid, Fr Eamon Crossan, Finbar Glackin, Jimmy Joe McGinley and chair Eddie McDevitt.

In 2011, they won the Donegal Senior Football Championship for the first time, with a 1–8 to 0–9 defeat of Naomh Mícheál in the final.

[8][9][10] On 25 September 2012, the Donegal senior team—fresh from winning the 2012 All-Ireland Senior Football Championship Final—were scheduled to visit Glenswilly; however, the visit was postponed due to time constraints which arose due to the huge crowds around the county eager to catch a glimpse of the team.

[4] Later that year they hosted the 2013 All-Ireland Football Series launch, held following confirmation of the four provincial winners.

By 2020, Neil Gallagher, Ciaran Bonner, Darren Mc Ginley and Joe Gibbons (all three-time SFC winners) had retired.
