Attested:  RC Adron

WhereAdron occurs in RC's harbour-estuary tour, when it has reached Hadrian's Wall.  It probably referred to the river Tyne, crossed by a bridge at Newcastle-upon-Tyne, which is generally assumed to be Pons Aelii in ND, where Aelius was Hadrian's family name.

Name origin:  The origin of the name Hadrian is uncertain, possibly from Adria, a port near the mouth of the river Po, south of Venice, which Pokorny (1959, p3) attributed to a PIE root *ad-ro- ‘water current’.  Adron, as written, matches Greek ἁδρος ‘thick, well-grown’.

Notes:  The closest parallel is the river Adrana, mentioned by Tacitus, now the Eder in Germany.
