I am not sure of the significance of the English town/city of Nottingham in connection with the Scots-Irish Presbyterian 'Nottingham Company' which arranged Granville land grants in NC. From what I have been able to glean, it seems most likely that the Nottingham Company gained its name because it was organised in the PA Nottingham township. The name of the township derived from the origins of its initial Quaker settlers. As a Quaker myself, it would of course be of considerable interest to discover that one or other of my immigrant American ancestors was in fact also a Quaker - but the facts are against that.
It should also be noted that the Pennsylvania Quakers did not exactly welcome the influx of Scots-Irish immigrants,

Nathaniel Grubb, a member of the Provincial assembly of Pennsylvania, and probably was of the Grubb family of ironmasters, once said in the Council Chamber, in reply to appeals for governmental protection against the Indians: "They are a pack of insignificant Scotch-Irish Presbyterians who, if they were killed, could well enough be spared."

not much intermarriage between Quakers & the Scots-Irish back then, I suspect ;-)
