Williams scored in each of No. 5 GCC's wins last week, recording her first two goals of the season.
She netted her first goal of the season in a 7-0 win at Niagara County CC and followed with another goal in a 2-0 win at home against SUNY Adirondack.
Seaton was a big factor in No. 3 GCC's two-win week, helping to keep the Cougars unbeaten so far this season.
His midfield play included a goal and seven shots, and Genesee defeated Niagara County CC on the road and SUNY Adirondack at home.
GCC will travel to Cayuga CC and host Jefferson CC this week.
