From The Kentuckians by Janet Holt Giles:
 

 The Cumberland Gap Area

 
The colonel [Henderson] has got a valid title if the [British] crown recognizes it.  Virginia and North Carolina have both repudiated him, but he hasn't sought recognition from them and isn't depending on it.  He has bought the land from the Cherokees, and it's his opinion that under the terms of the treaty at Hard Labor it was recognized by Britain as belonging to them.  He intends to set up as a proprietor under the crown.  He's purchased the land from the mouth of the Kentucky River along the boundary of the Ohio to Powell Mountain, down the ridge of that mountain to the Cumberland River, and down the Cumberland to where it flows into the Ohio.  He's already starting entering claims in the name of his company, which he calls the Transylvania Company....

...Cap'n [George Rogers] Clark is good friends with Patrick Henry [Governor of Virginia] and he said he was going to have a word with him about Colonel Henderson and try to find out which way the wind is blowing back there.

...to think of folks outside going their ownways, some in comfort and peace and even richness, deciding things in Williamsburg and Fort Pitt and Philadelphia, and even over in London, that would make things harder or easier for us here in the western country.

Note:  The Cumberland Gap was crucial to the settlement of Kentucky.  Pioneers were able to cross the Appalachian Mountains through that gap.
