White's sixth goal in four games put City in front, firing into the far corner from Williams' knock down.
Williams then doubled the lead when her shot from just inside the box was deflected past keeper Rachael Laws.
Paige Williams had a corner pushed onto the bar after the break as Blues continued to control the game.
