As the lyric of the song ‘Alexander Hamilton’ makes clear early in the musical, its title character was a son of a Scotsman whose family background was a spur to his own political success. In a sense, both the American Founding Father and Lin-Manuel Miranda’s fictional version of him are staging a homecoming, now Hamilton the musical is Edinburgh.

Yet Hamilton’s family history isn’t the only link the show has to Scotland.

For the best description of Alexander Hamilton’s early links with Scotland, we turn to Alexander Hamilton by Ron Chernow, the 2004 biography which fired Lin-Manuel Miranda’s imagination when he read it on holiday in Mexico – ironically, while he was meant to be taking a break from the success of his Tony Award-winning debut musical In the Heights after its arrived on Broadway in 2008.

Chernow’s book details how Hamilton was born on the island of Nevis in the Caribbean, most likely in 1755, to Rachel Lavien, a woman of British and French descent who was married but separated when she met his father, James Hamilton. In his late thirties by the time Alexander was born, James was the fourth child of eleven in the distinguished Hamilton family, who spent his childhood in Kerelaw Castle in North Ayrshire, with a view over to the Isle of Arran.

Three walls of the ruined castle still stand in the town of Stevenson, although they’re cordoned off to the public. James was long-gone by the time the Hamiltons moved out in 1787, however. With no chance of inheriting a title, he tried unsuccessfully to make it in the Glasgow linen trade, before lighting out for the West Indian islands and a hoped-for fortune in sugar. Again, it didn’t work out. Soon, Alexander was born.

Chernow describes young Alexander as “distinctly Scottish in appearance, with a florid complexion, reddish-brown hair and sparkling violet-blue eyes… his father’s Scottish ancestry enabled Alexander to daydream that he was not merely a West Indian outcast, consigned forever to a lowly status, but an aristocrat in disguise, waiting to declare his true identity and act his part on a grander stage.”
