Winsor Township is the next township straight west of Bruce, SD.
Look on that old 1897 map of Winsor Township you have. It can be found at:http://www.rootsweb.ancestry.com/~sdbrooki/maps1897/winsor.h...
John Piehl is marked in the NorthWest 1/4 of Section 17 on the map.
A look at a google map and it looks like it is on 455th Avenue, east side of the road; between 204th and 205th Street.
Hope this helps.
