Really fun ideas and very clever, but there are at least two equally valid solutions to the grid. Monica could swap over with Ana (or possibly Elsa).

Hi Malcontent. Again, thanks for the feedback. I don't think there is a Santa Elsa, at least not in well-known place names etc. You're perhaps right about swapping Monica with Ana though. Santa Ana is definitely a thing, but I can't think of any popular Spanish actress called Monica that works internationally (And I am half Spanish myself). Were you thinking about Monica Cruz?
