Thanks for that info....
Earliest English seems to exist in the names of hamlets, villages and towns, although I cannot offer examples just now.
And our various districts have their own terms from distant past.
This could make for a most interesting hobby.
Slightly tangentially, I am reminded of the passage in "1066 And All That", describing various Saxon kings:
"Canute had two sons, Halfacanute and Partacanute, and two other offspring, Rathacanute and Hardlincanute, whom however he would never acknowledge, denying to the last that he was their Fathacanute".
("Canute", or nowadays Cnut [sic
] - in fact had two sons called Harthacnut and Harold Harefoot).
There's also a poem:-
"Beoleopard*, or the Witan's Whail"
Whan Cnut Cyng the Witan wold enfeoff
Of infangthief and outfangthief
Wonderlich they were enwraged
And word war waged
Swaere Cnut great scot and lot
Swinge wold ich this illbegotten lot
Wroth was Cnut and wrothword spake
Well wold he win at wopentake
Fain wold he brake frith and crackë heads
And than they shold worshippe his redes
Swingéd Cnut Cyng with swung sword
Howléd Witanë hellë but hearkened his word
Murië sang Cnut Cyng
Outfangthief is Damngudthyng
*presumably a reference to Beowulf, something anybody reading English at Oxford had to study, in English very much like the above, until fairly recently.
(Infangthief and possibly outfangthief were apparently real terms in Saxon England.)
