One coat of arms used by Guy I of Clermont

Guy I of Clermont-Nesle (c. 1255 – 11 July 1302) was a Marshal of France, Seigneur (Lord) of Offemont jure uxoris, and possibly of Ailly, Maulette and Breteuil. He might have been a Seigneur of Nesle also, or used the title "Sire of Nesle" due to his family. Difficulties about the seigneurie of Breteuil are present, and the status of Ailly and Maulette in relation to Breteuil.
