Hi, Oloha, I have a book written by Stan Murphy titled:
The Best is Yet to Be. 175th Anniversary History of the West Cheshire Hospital, with memories from the Moston and Manor hospitals.
Published by C.C. Publishing Chester. ISBN Number 0 949001 27 9. It was published in 2004.
There are many photographs of staff in the book and you may get lucky and find some of your family.
I picked the book up in a second hand bookshop, but I believe that Chester Library has a copy. It would be worth phoning them and see if you can get an inter-library loan. You might even find a copy still if you google.
Regards
Kathb
