Hi, Perhaps the reason the family does not appear in the publication:
Families submitted family History/Stories to the Local History Book Project in the mid to late 1980's
If the family did not submit information / perhaps were not aware of the project - or ?
Unless others mentioned your family - as neighbours - or some family connection -
There may also be other Publications that have not been listed at the Alberta GenWeb Local History Book site.
Cheers, Stella
