Continuing on as some on the forum might be interested.
Historically the word Blenheim and probably the first use of the word to England and the English language appears to have come from the name of a small village in Bavaria, South Germany, on the Danube River near Hochstadt. In German that village is spelt and pronounced Blindheim.
Englishman John Churchill when he arrived at that village more likely spelt and pronounced the name as Blindheim, especially so as he was with a friend called Prince Eugene of Savoy who would have spelt and pronounced the name correctly as Blindheim.
At Blindheim village on 13 August 1704 one of the most important battles of the War of the Spanish Succession occurred, where John Churchill with Prince Eugene of Savoy defeated the French and Bavarians under Marshals C. Tallard and F. Marsin who were on the march to take Vienna in Austria, but on seeing John Churchill and Prince Eugene decided to dig-in and defend themselves, and the most defended position was at the village of Blindheim.
For those who are interested here are two eyewitness accounts of the Battle of Blenheim. The first is the Duke of Marlborough's own account of the battle, the second is the account by Dr. Hare, the Duke's Chaplain, at this link address.

Back in England when Queen Anne heard the news she was extremely thrilled, and when John Churchill returned back to England she awarded John the title of Duke Of Marlborough and also commissioned a Palace to be built for John and which became known as Blenheim Palace, that name came from the village named Blindheim but somehow the name changed slightly to Blenheim probably due to differences in language.
John Churchill and his wife Sarah Jennings (maiden name) were breeders, and their Cavaliers were referred to by different names particularly "Marlborough Spaniels" and "Blenheim Spaniels". But keep in mind that there were Blenheim coloured Cavaliers before the battle of Blenheim and before that name became commonly known and used.
I suppose the name and pronunciation could vary depending on what part of the world you are in, and maybe the more correct spelling and pronunciation should be Blindheim as referred to the origins of the name as seen on this webpage.

In relation to the Cavalier Lozenge that some might be thinking about. As the story goes Sarah Jennings was worried and waiting for news of her husband John Churchill who was away fighting at war at the small Bavarian town called Blindheim which occurred on 13 August 1704. Sarah had her pregnant bitch sitting on her lap, and in her anxiety she pressed her thumb on the little bitch's head, and when it later gave birth it produced a whole litter of pups all marked with a chestnut thumb print on top of their heads. But keep in mind that the Lozenge had been know to occur in Cavaliers before, and the Lozenge occurs in some of the other breeds that were used in the cross breeding development of the Cavalier.
