I've just posted a chart with six generations of Moctezuma's descendants, covering the period of about 1468 to the early 1600s. It is in the Files area under my name.
This chart should be considered a work in progress.
I've included only those individuals for which I can find some documented, historical evidence, and when possible, corroborated by more than one source. The basis for this chart is Chipman's "Moctezuma's Children," but with numerous additions.
There is some duplication in the list of Moctezuma's children. From one source (the Codex Chimalpahin), he is said to have had 19 children, but more than this are listed. Some of the daughters listed with both their Nahuatl names and baptismal names, from the sources I have I cannot yet match these together.
Corrections are welcome, as well as additions that can be documented.
