Attested: RC Coguveusuron
Where: Coguveusuron was a harbour estuary in East Anglia, listed by RC after Alauna (probably the complex estuary leading to Ipswich, with Walton Casstle by Felixstowe at its mouth) and before Durbis (Dover). Most likely it was the joint estuary of the river Colne to Colchester and the Blackwater to Chelmsford.
Name origin: A first element like Latin cogo ‘to assemble, to gather together’, plus a second element from PIE *weis- ‘to ooze’, like the river Weser in Germany, would be very appropriate for this joint estuary of two fairly sluggish rivers.
