I sought this book out as part of my genealogical research. I have Scottish ancestors that I knew little about before I started researching in earnest, and wanted a broad overview of the timing and causes of Scottish migration. Though it's a bit dated (published in 1994), this book provided a great example of what I was looking for.
The author, James Hunter, provides a continent-wide view of highland Scots immigration through a series of individual stories, loosely and somewhat haphazardly interconnected, and only roughly sequential. It's a very effective way to cover the geography, circumstances, and motivation of the migration of this ancient and proud people, and to illustrate both the breadth and the interconnectedness of their impact on North America.
The names, of course, can be hard to follow. Although Hunter generally uses Anglicized names (versus Gaelic), there are still an awful lot of people with identical surnames to keep track of. The author helps by putting relationship reminders, which I found useful.
I leave the book with a deeper appreciation of both the impact of highlight Scots on North America, and a deeper understanding of the arbitrariness and violence accompanying the post-Culloden restructuring of highlander life (the Highland Clearances, etc). So overall I enjoyed the book, and found it suited my purpose well. It's detailed but readable, and well laid out using clear prose (though of course written with a British - versus American - style and grammatical structure).
I have only two main complaints about the book, that kept me from giving it 5 stars:
1) the lack of maps was noticeable and impactful. The book presumes an awful lot of knowledge of both Scotland and North American geography (or the willingness to make regular excursions into Google Maps while reading). Two maps for each chapter (one on the "coming from" side in Scotland, and one on the "going to" side in the Americas) would help a lot. Those would be much more useful to the reader than the beautiful, but seemingly random, color photos. Honestly, even period photos of the people and places involved would be more interesting and applicable than the modern landscape photos that are included instead.
2) the lack of discussion of on-going migration within the United States. The book describes a lot of initial immigration to both the US and Canadian territories (both before and after the US War of Independence), but all of the on-going migration of Scot settlers focused on Canada ... e.g. the involvement of Scotsmen in the fur trade and exploration of the Canadian west, the trans-Canada railroad, etc. There is not a single page of discussion on the ongoing migration of Scottish settlers in North Carolina - who moved across the entire American South as it opened to European settlement. Surely there are stories there worth telling. But Hunter seems oddly focused only on Scottish migration within the British Empire...i.e. before the American Revolution or within Canada as a Commonwealth country. An interesting and notable omission.
Despite those misgivings, this is a solid book overall, and I thoroughly enjoyed it, and recommend it accordingly.
