Canon informs this story (and our reading of it) brilliantly. Names that are mentioned (or simply surnames because they're ancestors) and each event expands into so much more because this is about Godric's Hollow as much as it's about Bathilda, Griselda, and Eleanor.
And the lines, even some of the tiny, throw-away ones, just add to this sense of the story being a part of a much larger tapestry. Like this one, that gave me chills (on top of the goosebumps that I got from the mentions of Eliza Shunpike):
What should they want from you, anyway, that Rita Skeeter hasn't taken already?
I've spent a good part of today reading this story and consider it a day very well spent.
