What strikes me today is how Hrolf's ocular prosthetic altered how I saw him.
After Munich, we travelled to see Uncle Hrolf, still in Konstanz.
The central family myth about Hrolf Kramm is that he used his rank and position on the border with Switzerland to help Jewish families escape Germany.
This is something I understood implicitly when I insisted that all there was to know about my great uncle Hrolf was contained inside his glass eye.
I'm aware today that at some point during the years of informal inquiry, my ideas about the nature of Hrolf's prosthetic eye turned one variation.
Had Hrolf, during the war and because of it, suffered the guilt of Oedipus?
This is something Hrolf,43,from Wallasey has been doing for the last 10 years.
But it was purely by a stroke of luck that Hrolf became involved in such a major way.
Hrolf, together with his family, is a member of the Wirral branch of Regia Anglorum -Kingdoms of English.
Hrolf adds: ``We take the starting point as 902 which is when the Vikings from Dublin first arrived in Wirral -precisely where,no-one knows.''
Hrolf says: ``I have carried out extensive research and worked closely with the Jorvik Centre in York to ensure everything which we do is totally authentic.
