his is the fourth book in David Dobson's "Scots in the USA and Canada, 1825-1875," a series designed to compensate for the lack of official Scottish passenger lists to North America during the nineteenth century. Containing about 1,300 sketches not found in the prior books, Part Four brings the total number of descriptions of the Scottish men and women and their families who were part of this great exodus to about 6,000. In addition to skilled craftsmen, a number of the immigrants found in Part Four were dispossessed Highland farmers who had suffered as a result of the Highland Clearances, a kind of enclosure movement, or by periods of famine at mid-century.
