heh,
Hilde, you tear half of my argument apart with that
bil-boes reference. for indeed I was driving at that Bilbo's name, as part of the more light-hearted story about 'adventures', where lot of toponimy is just plain (The Hill, The Water, The Mountain, The River), is also just funny, whilst the LoTR, work of much wider scope, has layers upon layers of things to be seen and appreciated
But, well, one lives and learns.
On the other hand, I believe the said argument is still plausible, for all of the hidden meaning for 4 hobbits resides in real
personal names (exeption possibly Sam, but than, his short name corresponds with our Sam, though it be derived from Samuel and Hebraic, not Samwise and English), whilst 'bilbo' is stated by my dictionary to come (probably) from spanish town of Bilboa.
I believe therefore Bilbo's case to be a coincidence, whilst the other four cases to be there on purpose
Which, probably, proves how much of a swindler I may be.
Or, still, maybe not
