AN early goal from Fiona Lafferty set Donaghmoyne on their way to their third Dolores Tyrrell Memorial Cup success in Ballinamore, Co Leitrim.
The Monaghan champions produced an impressive performance to dethrone holders Carnacon.
Donaghmoyne set the agenda from the start, and driven on by the outstanding Courtney sisters, they attacked Carnacon from all angles.
The Mayo champions scored just twice in the second half and, were it not for a fortuitous goal from Natasha Beegan on 26 minutes, would have been in dire straits at the change of ends.
At the end of a hard-fought first half, Donaghmoyne led by 1-5 to 1-3, their goal coming when Lafferty followed up after Catriona McConnell's opening-minute penalty hit the post.
Cora Staunton did stop the rot with a well-taken score on seven minutes, but three frees from McConnell and a point from Hazel Kingham eased Donaghmoyne 1-5 to 0-1 ahead on 22 minutes.
But a freakish goal threw Carnacon a lifeline when Staunton's mis-hit free was spilled by Donaghmoyne goalkeeper Linda Martin, and Beegan toe-poked home.
However, any lingering hopes that the Connacht champions may have had of overtaking their old rivals were extinguished during the third quarter as Majella Woods (two), Catriona McConnell (two frees) and Cora Courtney all posted points to put the issue beyond doubt.
The last quarter saw Carnacon throw everything into attack but Donaghmoyne defended superbly and were not to be denied.
