Hi, If there were any surviving records for your father, then on production of proof of relationship you would probably be able to see them. However, I didn't make it clear enough in my last post, but access to other none relatives would not be possible with the 100 year rule. I would very much doubt that any medical records from WW2 survive. Most are destroyed, at the most 25 years after the last contact or when someone is known to be dead. There is a possibility some notes from his stay in Rock Ferry survive in his NHS Records. You don't say when your father died. But you could ask his G.P. Practice if they still have them or if they have gone to store, if so where? I am sending you a private message of a Wirral Website which may be able to help. As the records clearly show Rock Ferry, it is more likely to be St. Catherines Hospital rather than Clatterbridge. Although St. Catherines is in Tranmere. However we can't rule out that there was a facility in Rock Ferry. Have a look at my private message and I hope that this will help.
Regards
