My train of thought: From Holden --> Holden Caulfield (Catcher in the Rye) --> Books influential to adolescence --> A Separate Peace --> Gene Forrester --> Phineas --> Finny --> uspto.gov --> Live trademark search --> Finnie --> domai.nr --> "phinn.ie" --> back to uspto.gov --> "phinnie" is good to go

phinnie (phinn.ie) one more name to toss in your hat.
