Hi Steve. My father was injured in 1944 and spent some months at Plas Mariandir in Deganwy. I have a photo of him and other patients on the steps of the building and you should be able to see it on the original RootsChat . It must have been taken between 1944 and 1950. I am interested in the photos and post cards.
The Plas Mariandir building was built in 1935 as part of the Manchester and Salford Hospital Saturday Fund as a convalescent home, as there was no National Health Service at the time, and you paid a weekly subscription to be a member. I am assuming the military used it during and after WW2 for wounded soldiers etc, and this may be why your Grandfather was there.
Was your Grandfather from the Manchester area.
I guess from your Roots name you may be in Australia.
We visited Plas Mariaonly last week. It is in Deganwy near Llandudno, Wales.
I was shown round by Alan Williams, (Humphpaul on Roots) who now lives there as it has been converted into retirement homes.
I will message you my email address.
Regards Eric
