I like Robin very much: it's been on my top 10 since before I had a top 10! I also like William very much and Lewis somewhat. Holden used to be the Australian name for Ford cars, so that with Catcher in the Rye eliminates it for me, and Arlo is too Guthrie.
Robin Michael works very nicely. My cousin is Arthur Robin, always known as Robin (the ln starts with T - rather ART than RAT!)
