Edge types in this family
accepteddisputedcontested region

Generations run left to right, ancestors first, and the axis along the top is ordinal rather than linear: each band is one generation, labelled with the range of sourced introduction years it contains. A band reads “—” when no caliber in it has a year anyone published — the gap is the finding, not a rendering failure. Dotted arcs above and below the drawing are related edges — successor, drop-in, no-derivation — which are stored in a different table from lineage and can never form part of an ancestry path.

Curated overlays

A curated family label is an attributed opinion about grouping, not a node in the graph. No edge can point at one, and membership never affects ancestry.
