The village of St. Williams was formed by the owners of the farms on the east and west sides of the Townline Road between Charlotteville and Walsingham Townships, Norfolk County and officially dates from 1838 when the post office was established. The first settlement in the area dates back over two centuries to 1790.

The area is predominantly rural specializing in farm crops, orchards, forestry and sport fishing. Around the turn of the nineteenth century there was considerable industry in St. Williams making the name well known with its products sold across Canada. It has since settled back into its agricultural roots.

The crossroads of St. Williams' Main and Queen Streets are towards the top of the accompanying aerial view and Long Point Bay is at the bottom right.
