I recommend checking out what your hints mean in canon, because that's what we have to go off of. The first thing I did when I saw 1926 was head over to the Harry Potter wiki and figure out who was born in 1926. It's Riddle and three of his Death Eater pals, all from Slytherin, of which the obvious option is Riddle. Riddle fits the biographical details you give, with minor modification consistent with the upgrades people get from canon (a MOR Riddle might decide to not murder his family while still in school, for example). The canon rules for Houses appear to be "only Black is Noble and Most Ancient," and so we really don't have any idea which houses are the seven mentioned by Bones, and what the eighth missing house could be. Gaunt is a way better option than, say, Lestrange (where we know Lesath is alive).
In a fanfic, you should expect people to suspect that new characters are canon characters rather than completely new characters, which the person Bones is describing now appears to be (no canon births in 1927).
Thank you - I assumed it was a canon character, and came to this thread to find out who it was.
The next discussion thread is here.
This is a new thread to discuss Eliezer Yudkowsky’s Harry Potter and the Methods of Rationality and anything related to it. This thread is intended for discussing chapter 84. The previous thread has passed 500 comments. Comment in the 14th thread until you read chapter 84.
There is now a site dedicated to the story at hpmor.com, which is now the place to go to find the authors notes and all sorts of other goodies. AdeleneDawner has kept an archive of Author’s Notes. (This goes up to the notes for chapter 76, and is now not updating. The authors notes from chapter 77 onwards are on hpmor.com.)
The first 5 discussion threads are on the main page under the harry_potter tag. Threads 6 and on (including this one) are in the discussion section using its separate tag system. Also: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14.
As a reminder, it’s often useful to start your comment by indicating which chapter you are commenting on.
Spoiler Warning: this thread is full of spoilers. With few exceptions, spoilers for MOR and canon are fair game to post, without warning or rot13. More specifically:
