I must apologise for not getting onto Rootsweb sooner. Thank you for the messages that have been posted. I have had success!
I had looked at the Horrocks & Crewdson connection, but as my husband had no recollection of 'Horrocks' being mentioned when he was little, and also the towns did not link up with the family homes (nearness and travelling in those days), I discounted this.
Nick, your message mentioning Crewdson connection with Norcliffe Hall reminded me that this was the home of my husband's great grandfather.
Then Nell, your message suggesting looking at spinningtheweb.org.uk was just the right place to look. I found the Crewdsons I was looking for and got some good information.
Not only that, I also found information about the Bellhouse family and their business in the area - (John Crewdson married Nora Bellhouse - my husband's grandparents), so I am a very pleased with the finds.
I have now got a good grounding on which to continue searching.
Many many thanks for your help.
Suzy
