Arrowyn,
It occurs to me that, though not the period of your novel, this might be of general background interest to you

in case you think of writing another romance in a later era.
I particularly like the David Stuart of Garth correspondence - he was sometimes called "The First Highlander" in recognition of his attempt to collect authenticated tartans.
