Evidentiary standard
Family fortunes are only recorded where a named wealth desk publishes a standing family-level estimate; the source and valuation date are shown with the figure. Houses whose assets are held through charitable trusts, foundations, or sovereign vehicles carry no figure, because no verifiable personal total exists. Lineage entries are limited to publicly documented family members.
