Mary Kennersley/Kennersely of Loxley Park, London was the wife of Karl-August Barron de Bode, a retired Colonel in the Nassau Infantry of Louis XIV. In 1787, they purchased the salt factory at Alsace with Soultz-under-Forest, which they soon lost during the French Revolution. They were taken in by Catherine the Second of Russia. Some texts say that she was a decendant of the Duke of Glouchester and somehow related to Edward III. Her brother-in-law was Sneyd Adderley, a successful mine operator. The Baron later spent his fortune attempting over 35 years to collect a claim in Parliment to recover the 40,000 pounds he lost on the saltworks, but never was compensated by the British Government. I would guess that they both were born about 1735.
I believe that their daughter, Charlotte Elizabeth Catherine Maria Baronesse DeBode (1802-1885), married Alexander Cazalet (1793-1879), in St. Petersburg, Russia on Oct. 21, 1822. They both died in Lucerne, Switzerland. they had seven children, some of whom are the ancestors of the Cazalet in England today.
