 In Great Britain, Queen Victoria and her husband Prince Albert were Leopold's first cousins, while Leopold I of Belgium was Leopold's paternal and Queen Victoria's maternal uncle, and Leopold's brother was King Ferdinand II of Portugal, husband of Queen Maria II of Portugal.Leopold's candidature in the affair of the Spanish Marriages was used by France as the excuse to negotiate the hasty marriage between Queen Isabella II of Spain and her cousin Francis of Spain, at the same time as that between the son of Louis Philippe and the Queen of Spain's younger sister.Later, Leopold met Constanze Geiger, a common woman.
