Missing legends for natural children in some of the [genealogical tables] have been added. In some tables, the original uses the same symbol to indicate both natural children and skipped generations. In order to distinguish between them, the skipped generations are indicated by the § symbol, as that symbol is used for that purpose in the other original tables.
In the first table relating to the [succession to the Crown of Naples], [Jane], wife of Ferdinand I., is actually his second wife, and not the mother of his issue listed here. The original table lists this marriage twice; both instances are combined here for clarity.
The [Borgia genealogical table] is not historically accurate, but is presented here as it appears in the original. (See the author's comment on the Borgia pedigree on [p. 320].)
