A couple of suggestions:
Have you asked for some help here to find your family in the 1901 census in case they are ‘hiding’?
How do you know they had a pub around Church Street in Crook?
Have you searched newspapers in case there is mention of them.
There may be lists of licencees for the time frame (there are in some areas) so that might be worth pursuing.
If you wish to share their names and any details which may help locate them someone may be able to help. Timeline and known locations might be useful as well, if they moved about.
