a-Jeroth seems plausible enough in some ways, but I don't really see Foul gratuitously re-using that name when concocting a false history to be spread by the Clave.

That's how I've always interpreted it. Covenant was an honourary Lord in the sense that he was entitled to sit on the Council, but he didn't have the same status as a Lord. In prestige, his status was above theirs, but in practical matters and day-to-day affairs, he was totally out of the loop. So: ur-Lord - like a Lord, but not quite.
On the subject of Covenant's family: I hadn't actually noticed this until Gart brought it up, but I think he made a good point. Yes, Covenant's friends and other family may not have been directly relevant to the plot, but they must surely have been relevant to his isolation. Joan left him, and suddenly he was totally alone. Did he have no parents, siblings, close friends? No-one at all?
