It was pretty obvious it was someone from her coven, but it was possible she could have meant someone specific. Since Brigmore Witches, it is clear that that's not the case.

Not so much "knows" as "knows of." You find things written by Granny Rags in the Brigmore Manor, and she's pretty notorious in Dunwall, so it's likely Delilah is aware of her.
