The tree of readers
1099 – 1199 AH / 1687/88 – 1784/85 CE
Everyone the register knows who read to this person, and everyone who read to them, generation by generation. A link drawn from an uploaded document is solid; one taken from a printed reference work is dotted and names its source.
The tree was cut at 600 people. Start from a name further down, or ask for fewer generations, to see the rest.
