10 Oldest Characters In The Harry Potter Universe
6. Griselda Marchbanks
Age: 147+
Professor Griselda Marchbanks has a unique claim to fame in that she actually invigilated both Harry Potter and Albus Dumbledore's Hogwarts exams.
In the Order Of The Phoenix novel - while presiding over Harry's O.W.L. tests - she mentioned that she personally oversaw Dumbledore during his Charms and Transfiguration N.E.W.T. exams. Dumbledore sat these when he was 17 or 18 years of age, meaning that Professor Marchbanks has to be around 10-plus years older than him in order to be qualified and experienced enough to be a full-time invigilator.
So, with a birth year around 1871 or earlier and no record of her having died, Marchbanks could still be alive today, putting her at the ripe old age of 147 or more. Is there a wizarding retirement home somewhere?
