Duke Of Brittany

4 recorded holders. ← all offices

The succession the rolls themselves record for this office, earliest first — a finding aid drawn from the roll text, not an authoritative fasti. Spelling variants of one holder now fold together where the volumes' own printed indexes attest them (“Burghers” and “Burghersh” are one man when the editors say so); the opposite case — one name hiding two men — is proposed from the same indexes and from matched identities, and separates only after human confirmation. Until then a shared name lists as one holder, and the list can be checked against printed succession lists (Fasti / VCH).
