|A young Victoria - I would!|
The "Widow of Windsor."
Queen Victoria ascended the throne in June 1837 and reigned thereafter for 63 and a bit years.
She was the last of the Hanoverian monarchs (The Georges) and her marriage to Albert of Saxe-Coburg-Gotha meant that her descendants had a rather unfortunate surname come the First World War.
She was the first monarch to live in Buckingham Palace.
A common anecdote that Queen Victoria did not believe sex between women was possible and so refused to agree to its illegality is probably bollox. (but just in case ... thanks Vic!)
