Countess Maria Fransisca of Thürheim, ‘Auntie’ of Leontine of Salburg, is virtually an unknown individual, located in a periphery of the Salburg-Thürheim genealogical tree. She was one of the daughters of Count Kuefstein, thus Thürheim must have been her married name. Her sister was married to Field Marshal Salburg. Sadly, I have not yet found out how their husbands were placed in the pedigree of the Thürheims and the Salburgs.
You may wonder why I have concerned myself with such an obscure person of seemingly no consequence. Well, she is ancient, that’s why. Through some indirect evidence, I am able to put her date of birth in the 1680s, which makes her a contemporary of the core characters – first of all, Prince and Princess Schwarzenberg, but also some others whose names cannot yet be revealed. Besides, unlike them, she was still alive in 1757 and therefore exactly the person the narrative needed – a living memory and eyewitness of a time gone by and a generation passed away.
