Does the solution to this new mystery cast light on an old mystery?

Last Wednesday the rumours were going around about human remains found on Musselburgh Old Golf Course (on Musselburgh links, within the circuit of Musselburgh Race Track), and the local papers at the weekend confirmed that this was a human skull, of some age, which was being examined by archaeologists from Dundee University.
Now this news story:

reveals that the skull, of a 'mid-to-late teenage' woman is 2500 years old, and perhaps comes from an Iron Age cemetery --- presumably of the Votadini?.
So that's the 'new mystery'; the 'old mystery' is that one of the holes on the Musselburgh course is traditionally called 'The Graves', and the local lore is that this is because some of the fallen from the Battle of Pinkie Cleugh (1547) were buried in this area.
I was always puzzled by this, because the core of the battle was at least half-a-mile to the south, on the 25m high plateau between Inveresk, Carberry and Wallyford, and the main slaughter occurred in a corridor stretching away westwards towards Edinburgh, Dalkeith and Leith.  The only well-attested burial site was discovered in the 19th century during the construction of the East Coast Mainline railway, which crosses this plateau in a cutting.  William Patten describes such a burial of English dead on the battlefield itself, and also says that, when he returned to the scene a week later, some Scots bodies had been buried in Inveresk churchyard, but many still lay where they had fallen.
So is it possible, that the origin of the 'Graves on the golfcourse' legend is that, at some time, other Iron Age burials have been uncovered their, and that those who found them simply assumed without much evidence that they were the remains of some of the dead of Pinkie Cleugh?
