Queen Victoria's maternal grandfather (i.e. her mother's father), Francis, Duke of Saxe-Coburg-Saalfield, had four sons, all of whom were her uncles:
# Ernest I, Duke of Saxe-Coburg and Gotha # Prince Ferdinand of Saxe-Coburg and Gotha # Leopold I, King of the Belgians (who was clearly her favourite uncle) # Prince Francis of Saxe-Coburg-Saalfied However, Queen Victoria's paternal grandfather (i.e. her father's father), George III, King of the United Kingdom, had nine sons, so she had eight uncles through him:
# George IV, King of the United Kingdom (previously The Prince Regent) # The Prince Frederick, Duke of York # William IV, King of the United Kingdom (previously Duke of Clarence) # The Prince Edward, Duke of Kent was Queen Victoria's father # Ernest Augustus I, King of Hanover (Duke of Cumberland) # The Prince Augustus Frederick, Duke of Sussex # The Prince Adolphus, Duke of Cambridge # The Prince Octavius # The Prince Alfred So Queen Victoria had twelve uncles.
