Attested: RC Adron
Where: Adron occurs in RC’s harbour-estuary tour, clearly referring somehow to Hadrian’s Wall. It might refer to the Wall itself, or to the river Eden past Carlisle (Ptolemy’s Ἰτοὐνα), or to the river Irthing towards Banna (Birdoswald). The Roman fort at Newcastle-upon-Tyne is generally assumed to have had a bridge referred to in ND as Ponte Aeli, where Aelius was Hadrianís family name. So maybe Adron just meant the estuary of the river Tyne.
Name origin: Adron, as written, could be from Greek ἁδρος ‘thick, well-grown’, the likely origin of the name Hadrian. However, if it does apply to a river, maybe it comes from PIE *ad-ro- ‘water current’ (a poorly attested root on page 3 of Pokorny) which may show up in the Adriatic Sea and in Portus Adurni, but has its best parallel in Tacitus’s river Adrana, now the Eder in Germany
