Georgina Muir Mackenzie

Georgina Mary Muir Mackenzie, Lady Sebright, Baroness d'Everton (9 September 1834 – 24 January 1874) was a Scottish activist, writer and traveller. She was arrested as a spy with Paulina Irby, with whom she raised the plight of Christians in the Ottoman Empire, and published a book that William Gladstone said was "the best English book I have seen on Eastern matters".

Mackenzie moved with her family to London in 1855 where she met Paulina Irby. She set out with her new companion to visit spa towns in Austria-Hungary and Germany in 1857. Despite Mackenzie's perceived family weakness for consumption, they travelled alone relying on their British passports and planning to travel by hay cart. They now had a purpose as they traveled in the Balkans investigating the conditions and both became supporters of Serbia and the southern Slavs as they saw their conditions under the perceived poor government by the Ottoman rulers. They were particularly concerned by the plight of Orthodox women and girls who found they had poor access to positions and schooling. They published Across the Carpathians which explained how they had been arrested for spying.

Mackenzie took vacations in Corfu in 1862 and 1863 where she met her future husband. and died four years later.

Legacy Mackenzie and Irby's book went to a second edition with a foreword by William Gladstone as the Serb Christian population revolted against Ottoman rule starting the year after Mackenzie died.
