Froghorn, i don't have copies of these letters.They were ones i came across from time-to-time and i was always impressed with both the writing skills and the mastery of the language. I never developed a good writing hand myself and i am envious of any who have one.
I see my wife putting a quill to parchment and her lines flow so beautifully, while mine strike a strange resemblance to a combination of ancient Sanskrit and a prescription written by a doctor with a tremor. Try Googling "Old miner's letters" and see what pops up.The library can be of help as well if you can't find anything on line.
