I've lived on this side of "the puddle" since 1987 and have rarely met a native that is NOT interested in Scotland and it's history. Many are fascinated by the clearances, Scots-Irish connections and the history of early Scots migration.
Myra Vanderpool Gormley wrote a good overview "Migration Patterns of Our Scottish Ancestors" for American Genealogy Magazine that was re-printed in Genealogymagazine.com http://www.genealogymagazine.com/scots.html She writes of the whys, where from to where to, and the early Scots contribution to the fledgling nation. Interesting reading and a good jump off point for more in depth studies of various settlements.
Another interesting, and much longer article "Scotland's Mark on America" by George Fraser Black can be found at http://www.scotlands.com/usa/3.html You need to take your time reading this one. Lots of information to sift through.
