Buried Treasure

I take Ned not having thought of Rhaegar as to mean he hadn't dwelt on Rhaegar's character - in that chapter he was thinking about whether Rhaegar was the type of man to frequent brothels. A lot of the mentions in other chapters were facts about events involving Rhaegar, often for the benefit of the reader, so to Ned's mind he might have been recalling Rhaegar, but not thinking about him

Yes. On the page Barra there is this Varys quote There was another bastard, a boy, older. I took steps to see him removed from harm's way ... but I confess, I never dreamed the babe would be at risk. A baseborn girl, less than a year old, with a whore for a mother, what threat could she pose? Perhaps the section should be on known status of his bastards, or persecution of them, instead? All of Robert's children are accounted for on his page under progeny and on the family tree, but only the 5 whose names are known have separate pages. He had twins to a servant at the Rock, that I think Cersei had killed years ago, but they are listed just as 'unnamed twins', with no further details. Making it a general persecution section would also allow you to include the threat to Edric Storm from Stannis / Mel.
