Cockie, greengage, I’m sure there are many paths to enlightenment, but mine was this. Once the grid was filled, and the circled cells completed, I made quite sure I had the correct extra words to generate the right message. That’s crucial. Then you need to work out how to implement it. When you do, it should lead you to the title, and thence the dedicatee. Then the name spelt by the asterisked cells plus one letter should also make sense.
I think you could go down a fair few rabbit holes in looking for the puzzle’s dedicatee before you have the title.
