Mancunian

Current among the Britons, the name of Manchester was equally received and retained by the Saxons. […] [M]oſt of the more remarkable objects about the town, at this period, exchanged their Britiſh denominations for Saxon. And even one of the rivers, even the monarch of the Mancunian currents, now reſigned up its original name of Beliſama, and received another; from the marſhes and marſhy meadows, that ſkirt its channel on both ſides in one continued line to the ſea, obtaining the deſcriptive denomination of Merſc-ey, Merſ-ey, or marſhy water.
