I can find cuts that work for Column 1 while also finding the second (shorter) name. The approach seems consistent with the theme.
All well and good, except that the resultant grid entry containing the second name has an extra letter at the end. As far as I know, the entry is thus not a word - and it is not (just) the surname.
Is this OK because it's still somehow a "thematic entry"?
All others are words or the other surname.
I hope this makes sense and means that I've got there!
