Medieval genealogy in context
Why medieval lines aren't always provable
Medieval Welsh genealogy isn't always linear or provable. Some family lines were recorded centuries after the events. Others changed due to shifting political alliances, conquest, or clerical error.
How Gwirachau handles it
Gwirachau treats all genealogies with care, clearly labelling source quality, known interpolations and contested lines. This transparency helps modern researchers separate legend from lineage.
Gair i gall A word from BranSome medieval family lines were written down centuries after the people in them lived.
That's why every line here carries a source label.
