Wolves had scored 31 FA Cup goals through the opening four rounds of this season's competition, including 14 in the third round alone. But this was a very different kind of test for Dan McNamara's Women's National League North side.
Elisabeth Terland had opened the scoring midway through the first half, a lead which Galton doubled before the break - marking her landmark 150th United appearance with a goal, only the fourth player to reach that milestone after Ella Toone, Millie Turner and former skipper Katie Zelem.
The third and fourth from Aoife Mannion and Toone respectively came in quick succession after half-time, before 17-year-old Mared Griffiths made it a really special debut with two late strikes of her own.
