Perhaps the British of the 7 Years’ War would harken back to 100 Years’ War, to their defeat at the hands of Joan of Arc at the original (old) Orleans. They might want to avenge that costly failure to take Orleans which, according to Wikipedia (see below), prevented them from conquering all of France by wiping out all the French place names in Louisiana.
By taking New Orleans, they would thereby also have all of Louisiana fall into their hands and irrevocably weaken, if not eliminate, the French menace forever in North America. So why not eliminate the very names too ?
Louisiana could become Plantagenetia, after the English royal family, the Plantagenets, at the time of the 100 Years’ War. As for their present King George II or III, “Georgia” was already taken and “Hanoveria” doesn’t recall heroic English warrior kings like the glorious history of the Plantagenets does .
New Orleans could be renamed Lancastria, after
John of Lancaster, the English regent, for Henry VI. Lake Pontchartrain could be renamed
Lake Agincourt, for one of the greatest English victories in history.
Baton Rouge, meaning “red stick” in French, could be renamed for another 100 Years’ War hero, the Black Prince. Or “Prince Noir” if the British really wanted to stick it to the defeated French.
Biloxi and Mobile could retain their names since they were derived from Indian tribe names and not obviously French.
Wikipedia said:
The
Siege of Orléans (12 October 1428 – 8 May 1429) was the watershed of the
Hundred Years' War between
France and
England. It was the French royal army's first major military victory to follow the crushing defeat at the
Battle of Agincourt in 1415, and also the first while
Joan of Arc was with the army. The siege took place at the pinnacle of English power during the
later stages of the war. The city held strategic and symbolic significance to both sides of the conflict. The consensus among contemporaries was that the English regent,
John of Lancaster, would have succeeded in realizing his brother the English king
Henry V's dream of conquering all of France if Orléans fell. For half a year the English and
their French allies appeared to be winning, but the siege collapsed nine days after Joan's arrival.
