Neither Meredith nor Margaery should be familiar to Delirium, I would think, since they're both comparatively sane and haven't had any issues I can think of. Sacharissa has had her... moments of madness, but it's been agreed after much discussion that the Endless probably know the immortals who work the Disc, but they don't do it themselves, so I think Del wouldn't know her. So here's the pertinent one:
Veronica is usually sane, as far as teenage girls go, but she's been under a lot of pressure in her past. Following the murder of her best friend, she was sent to see a psychiatrist for a while, but that was at her mom's insistence; she didn't feel she needed to be there. For a year and a half, almost two years, after Lilly's death, Veronica had vivid memories and waking dreams -- she would tell you they were just her imagining things, working out clues by imagining what Lilly would say, but they were closer to hallucinations -- of Lilly Kane. She can be pretty paranoid; the life she's lived has taught her she has to be, since she's nearly died a couple of times. But again the information probably most pertinent is that the hallucinations were about Lilly (who is now on the island as well).
