Maryport's Catherine O'Donnell scored her first try for England as the Red Roses overcame Ireland at Twickenham Stadium in their final Quilter Internationals test.
The hosts scored seven times, running out 37-15 winners after victories earlier this month against USA and Canada.
Darlington Mowden Park Sharks hooker Heather Kerr got England on their way after seven minutes, dotting down from a driving maul with further scores from Kelly Smith and Vickii Cornborough.
Eimear Considine and Lauren Delany crossed on the stroke of half-time for Ireland, but England went in 15-10 ahead at the break.
Lydia Thompson touched down for the first points of the second half then showed her class to break a tackle and race in from her own half.
Irish pressure eventually saw Claire Molloy score but it was the Red Roses who were victorious as Thompson finished off a smart handling move for her hat-trick before O’Donnell bundled over in stoppage time.
