On 21 September 1869 at the Château de Marchais (which is still in the possession of the Grimaldi family today) in Champagne, Prince Albert was married to Lady Mary Victoria Hamilton (1850-1922), of Lanarkshire, Scotland, a daughter of the 11th Duke of Hamilton and his wife, Princess Marie of Baden.
Within a year of their marriage, the couple's only child (Louis) was born, but Mary, from the hills of Scotland, disliked Monaco and everything Mediterranean.
