Two suggestions.

First, try contacting the Cathedral, which is HERE, where there are links to e-mail the VISITORS' DEPARTMENT at vis&profficer@cathedral.org.uk or the EDUCATION OFFICER (Saul Penfold) education@cathedral.org.uk

Second, try a Google search on Medieval Reenactors UK. There were so many results my eyes glazed over-- but you should be able to find either the group or an association or event that can help find them.

Don't forget to come back and tell us all that you learned, and please! Encourage them to visit Mudcat.
