muraria - thanks. I have the 16 clashes resolved (very neat!) and that's where I'm stuck. I know the entries for the other two entities, but I can't fathom out who they are. Rather than give too much away here, would you be willing to lift the veil a bit to mrbaddie@btinternet.com?
I'd welcome the hidden surname (can't find any of the obvious ones) and what goes in the middle. I'm being very thick today.
