I bought a medieval seal matrix in recently ,and I want to find more history about it and it’s original owner. The seal maybe date back to 11~13 th century ,and inscription shows ➕ SI ROBERT BESING ,which means seal of Robert Besing,and the Image of the middle side is iris flower ,and the seal were reported found in nearby Durham of England. I tried to search some information about him ,but the information is limited on internet ,I only found “Von Besing”is a Germanic origin surname ,plus before 13th century the seal matrix usually only hold by nobles ,until 14th century being common for general Classic,and the symbol of iris might related to France royal or a member of some basic nobility . Since the skill of seal craving is not very fine ,so I suspect that the origin owner might be a knight or a baron (?)whom might be a France or Germany or a Anglo-Norman ,I’m not sure am I correct ? I hope someone could provide me about British Besing family history ,or even better to provide me the medieval times document which mention Robert Besing. Please see the picture below Thanks a lot.
