Hi, Perhaps someone will be able to search City Directories - Criss Cross Directories eg Hendesons/ Wiglays etc for John/Jack TURNER and his brothrs Frederick TURNER - Harry TURHNER.
They show Name to Address - Address to Name -
will show names of all persons of age [perhaps not females at that time ]may show occupation/business.
Prhaps John, Federick , Harry TURNER - served in WW1?http://www.collectionscanada.gc.ca/databases/cef/001042-100....
Perhaps: applied for Homestead?
