The Division 5 Final produced a minor classic as St Maur's withstood a persistent Parnell's side to prevail by 2-1 to 0-4 in a highly entertaining encounter.
The winners gained much momentum from their semi-final win over St Peregrine's on Saturday and they maintained that form with Culann Noonan impressing throughout from midfield.
He received some valuable support from the likes of Matthew Hughes, captain Tom O'Neill, Ciarán Barry and Glenn Weldon, and Kevin O'Connor's goal lifted the spirits of the Rush club at the start of the second-half.
Parnell's, who beat Ballyboden St Enda's B in the semi-final, enjoyed the majority of possession with Keith Campbell a rock at centrefield alongside Mark Herron, while Liam Togher and captain Daniel Geraghty were equally influential for the Coolock lads.
Most of the play was directed towards the St Maur's goal in the second-half with Aaron Mills, Seán Quinn and Zak McCloskey driving Parnell's forwards as they drew level at 0-4 to 1-1 with 10 minutes remaining, much to the pleasure of inspirational manager Jane Murphy.
However, the game turned when Ciarán Archer received possession and produced a sublime shot beyond the excellent Nathan Salmon for a fitting conclusion to a high-quality spectacle.
