Cyclonic,
pN can fill the gaps in but here is a rough go at sires outside of the Northern Dancer line
From the same Pharos - Nearco line to Nasrullah but not ND, the key flagbearer must be Dalakhani.
From the Nearco-Royal Charger line Dubawi is the new star, Dynaformer is important and Intikhab is making a bit of a name. Tagula the sire of Canford Cliffs is of this line.
From the Phalaris (sire of Pharos) but not the Pharos line - to Mr Prospector line is Street Cry, Zafonic, Zamindar, Elusive Quality, Medicean and Kings Best.
Non-Phalaris
Diktat is a member of a unique line going back to the least dominant of the original 3 sires.
Monsun comes from the old Bahram line and you can see why UK/Ire breeders are using him
There will be many others, but Northern Dancer (1st) then Phalaris (2nd and ND's great great grandsire) are dominant to a level probably not seen before. But as Tony Morris has said 'People tell me most great horses decend from Phalaris, only trouble is most bad ones do as well'.
