Dear Kirwan,
I owe you thanks for passing me all this information. Your interest and knowledge in the subject suggests more than a genealogical one. Are you connected with one or other of the manufacturers?
As you might have already guessed, I grew up in Stilton and have known a number of the decedents of people mentioned in the historic texts above. As you can imagine,in Stilton, the subject of the origins of Stilton Cheese is a hot topic and always has two sides. One that quotes from the acknowledge sources (usually the one that claims cheese was never made in Stilton) and the other that goes "well my granddad said his granddad...."
Recently some information was passed to a group in the village and I was asked to verify that information hence my knowledge of Richard Bradley.
I have not yet managed to find the c1690 quote I previously mentioned. Nothing written in your previous text sounds like that which I have seen even though the content is similar. I have it in mind that I read it in a Thesis or Dissertation found in a University Library, possibly in New York. I usually save all sources although in this instant I might have decided not to save an entire Thesis for one paragraph. I will keep looking.
Should you find more information on the subject I would be pleased to here it be it either for or against the the origin being Stilton.
All the best - FS

Added : See The English Dairy Farmer 1500 - 1900 by George Edwin Fussell pages 223,224,225,226. It contains a description of 'New Milk' cheese which sounds close to the recipe reported by Bradley and dates to 1600 approx'. The method described would certainly lead to a very slow rate of production.
Page 247 contains an interesting rebuff to the attribution to Mrs Orton and also Guy Paget's attribution to the 5th Duchess of Rutland. ...oh and it can be found on Google Books
Added : Country Housewife and Ladies Director - Richard Bradley page 67 & 73 - This contains some of the references I have seen mentioned in the missing Thesis although none that refer to the period 1690-1710. I will keep looking.
Added : Last one for today - The Monthly Magazine 1800 page 462 contains some odd and oblique references that might be worth following up. If correct could put Stilton cheese origins to the reign of Elizabeth I.
