Kabeja and Stan.
Oh my goodness! I am the person who replied to Kabeja's initial enquiry saying that my Gt Grandfather had also died in an Asylum of 'General Paralysis'. Although I obtained his admission papers from the local Archives - I hadn't realised there may also be other papers concerning his medical condition whilst there. (I have no idea why I didn't think of that - it was such a shock to find he had died in the Asylum anyway - and to read the Doctor's admission notes.)
Now - from what you and Stan have said - I am even more horrified!
I have just looked up 'General Paralysis of the Insane' - and amongst other things Wikipedia states;
Delusions, common as the illness progresses, tend to be poorly systematized and absurd. They can be grandiose, melancholic, or paranoid. These delusions include ideas of great wealth, immortality, thousands of lovers, unfathomable power, apocalypsis, nihilism, self-blame, or bizarre hypochondriacal complaints.
My Gt Grandfather's admission includes a statement from his Doctor of things my Gt Grandfather had told him -- utterly ridiculous and fanciful statements as to what he had done, where he had been - his important job etc (none of which were remotely true). So he was most certainly suffering from delusions.
I can see I am going to have to delve again and see if other papers exist at the Archives.
Many, many thanks for the information and the update to both of you.
