And let’s see if we can guess what you’re reading. Then it’s your turn.
I just finished a book with Ned Willard, Rollo Fitzgerald, the Earl of Shiring (that should be a big hint) and Queen Elizabeth.
Ken Follett, A Column of Fire
Sunny D, you’re supposed to follow suit, thusly:
Ben Mears, Mark Petrie, Susan Norton, Matt Burke
Salem’s Lot, by Stephen King
Pangloss, Martin, Cunegonde, Cacambo
I was waiting for confirmation that I had the right book… alas and alack.
Sunny was correct! Keep going!
Prof Periwinkle, Candide.
Lisbeth, Mikhail, Erika, Armansky
The Girl with the Dragon Tatoo. That first name is a dead giveaway 
Alvin (x2) , Faith, Little Peggy, Taleswapper, Measure
Looks like you stumped us? Any more clues?
Alvin Prentince, Orson Scott Card - not sure if you had a particular book from the series in mind but I think that one has the characters you listed
Max, The Albino, Fezzik, Vizzini
Princess Bride
Ignatius J. Reilly, Myrna Minkoff, Irene Reilly
A Confederacy of Dunces
Aleksander Buda, George Wilson, Burim Graziani, Tobias Rothman
Okay, I added another character, which gives it away.
Aleksander Buda, George Wilson, Burim Graziani, Tobias Rothman, Pia Grazdani
Nano
Grag Hamcrusher, Lance-Constable Salacia von Humpeding, Lady Sybil Ramkin and Lord Vetinari
I was going for Death Benefit, in which Rothman dies, so I don’t know if he’s in Nano, which is the second of two novels with Pia. In a flashback maybe, I haven’t read it.
PP’s effort:
Grag Hamcrusher, Lance-Constable Salacia von Humpeding, Lady Sybil Ramkin and Lord Vetinari
Although on a quick flick through I couldn’t find Grag, PP’s must surely be Thud!, unless Sally comes back in a later book.
Telemark has mine basically right - I was thinking of the first book, Seventh Son, but in fact I think all those characters pop up in at least the first three of the series.
And now for a different genre…
Jane, Elizabeth, Fitzwilliam, Charles.
Pride and Prejudice
Hazel, Fiver, Blackavar, General Woundwort
Watership Down - one of my all-time favourite books (even as an adult).
Arthur, Marvin, Ford, Tricia
- Hitchhikers Guide To The Galaxy*
Mother, Marie, Raymond, The Little Robot Woman
The Stranger
Sonny, Duane, Jacy, Sam the Lion
The Last Picture Show
Luther, Nora, Blair, Enrique
