It references the Paston family, a well-known family in Medieval England, who lived in Norfolk.
A brass plaque, in memory of Anna Paston was discovered in Oxnead church in Norfolk last month, by archaeologist, Matt Champion.
Anna Paston's brass was tucked away between two large tombs, obscured by the communion rail.
Mr Champion said the greatest surprise was that she was a member of the "most researched family" of medieval England, yet was unknown to historians.
The Paston family are infamous for their rise from peasantry to aristocracy in just two generations.
Many of the properties they lived in still survive, as do the institutions of which they became benefactors.
