It sounds like others have found the uncommon two fairly quickly compared to everything else. I somehow have the duo, their statement, and the cryptic representation confidently.
I have a rather long third name that other comments in this thread lead me to believe is one of the uncommon ones (even though it looks common enough to me). I've checked every row, column, and diagonal for sensible names or even the other cryptic representation (since I suspect I know the length) and nothing has shaken loose.
Would anyone be able to help me cross the finish line?
