Recent Events
A Game of Thrones
Lord Eddard Stark uses the book while looking into the death of his predecessor as Hand of the King, Lord Jon Arryn.[2]
After reading that historical marriages listed in the book between Baratheons and Lannisters all resulted in black-haired children, Eddard concludes that the children of Queen Cersei Lannister—Joffrey, Myrcella, and Tommen Baratheon—were not actually fathered by King Robert I Baratheon.[1]
Quotes
Eddard: I should be curious to examine the book that you lent Jon the day before he fell ill.
Pycelle: I fear you would find it of little interest. It was a ponderous tome by Grand Maester Malleon on the lineages of the great houses.[3]—Eddard Stark and Pycelle
Game of Thrones

The version of the book used in the television series Game of Thrones includes non-canon members of House Baratheon, House Hunter, House Karstark, House Royce, and House Umber, as well as the non-canon Houses Blackbrow and Greenleaf.
Notes
- ↑ Although Eddard Stark describes the book as being "over a century old" and that "scarcely a man now alive had yet been born when Malleon had compiled his dusty lists of weddings, births, and deaths", the book states the marriage between Gowen Baratheon and Tya Lannister occurred "some ninety years ago". Therefore Eddard's comments should not be taken literally.
