Sinclairville or Gerry, New York Family: 1920 or So

This photo is from Kenneth Olmstead's album. I cannot identify the people. I scanned a smaller area to try and get a better image of the people but it needs photo editing, and I don't have such a program. The woman on our right, standing by the corner of the house, could be an Olmstead but I'm not sure. Other possible families are Damons, Strongs, or McCulloughs.
