This book is the first consolidated work that contains the entire ancestral tree of the American McQuains dating back to their Scottish progenitor, Alexander McQuain. Pictures, records, and stories of this prerevolutionary family, as they dwelled in America, are now recorded forever for future generations. This book also discusses the Gaelic origins of the McQuain line based on a multitude of sources concerning Irish and Scottish history. These sources seem to point back to Irish high kings, Norse influence, and the Scottish Highlands. McQuain men possess haplogroup DNA that points back to the high kings of Ireland and the name MacCuinn. These MacCuinns are recorded as moving into Scotland as MacQueens. Once in Scotland, the MacQueens are documented as possessing lands in the Isle of Skye and Inverness. The name, McQuain, is recorded in birth records in both of these places. This book contains ancient stories about these distant ancestors.
