When "De Situ Britanniae" was debunked as a fraud in 1845, Roy's misguided placement of Trimontium was retained by some historians, though he was no longer cited for his contribution. Furthermore, some historians not only accepted Roy's placement of Trimontium, but also returned the town to the Selgovae by moving their territory such that they would be near Eildon Hills. Ptolemy's placement of the Novantae in Galloway was retained, and since Ptolemy said that they were adjacent to the Selgovae, Novantae territory was greatly expanded beyond Galloway to be consistent with this thesis, which survives in a number of modern histories.
