If your father and /or any other family members were living in the house in 1930 and earlier you could find them in the US Census records, which include addresses. They're available via ancestry.com.
Here's ancestry.com information on those databases:
The U.S. has taken a census of its population every ten years since 1790. The most recent census available to us at present is the 1930 census, due to a 72-year privacy restriction. While the questions in U.S. census records varied from year to year and in state censuses, from state to state, you can find information like names of other household members, ages, birthplaces, residence, occupation, immigration and citizenship details, marriage information, military service and more.
If you have a chance to go up there, the local library might be a resource. They may have old phone books for the time that your father's family lived there.
Or you can look at road names on google maps and that might refresh your memory--if you google "Walker Valley NY" and look at the map view (not the satellite view) it will give you the town boundaries so that you know what roads to look at. Luckily Walker Valley isn't a very big area which makes it easier. Also if you look at Bing Maps - Driving Directions, Traffic and Road Conditions
and look at the map using the "birds eye view" you'll see aerial photographs of the area--you can zoom in and look at actual houses. If you zoom in close enough you can see features like separate garages, how many windows, architectural styles etc. Also if you can remember any features like a dead end road, or a pond, looking at the map may help you recognize the house.
