Hi Sandra,
I have the same problem with Wales place names.
Red Doles in Huddersfield I only heard of the other day and I live there! its local name today Cantor Lane where the fair used to be by the Football ground and be going there 60 years. So your not the only one.
The river Calder is a long steep valley that joins the River Air at Castleford and it source starts Rawtonstall (Stream) near Blackburn in Lancashire. Flowing down to Ba-cup then Todmorden where it becomes a river when it joins it other large stream from Burnley. From Todmorden to Halifax is a very long stretch of about Approx 15 miles with Hepenstall and Hebden bridge halfway (See google Maps)
Walsden is near Todmorden on the Rochdale road from.
Walden, Old Pool Bank, Pool In Wharfedale, Idle, West Yorkshire LS21, UK
Walden Dr, Queensbury, Bradford, West Yorkshire BD9, UK
Ogden is North-North west of Halifax on the Keigthley Road
on the Moors above Hebden bridge, 
and a connecting trunk road the A 6033 and B6141 Oxenhope Hebden bridge to Denholme to Queensbury above Ogden moor (farms) and Village.
The Cockroft family may still own this garage and other ventures/businesses/farms. Thus maybe worth writing blind to them. Directories 192 or 118. websites or Yellow pages as business.

Well Sandra! we have burned a lot of posts now in this and I'll check that polling year at Halifax library over the coming weeks and the Zion church yard. Also anything else. I be back in Yorkshire tomorrow.
I'll post any findings.
Regards for now!
