It is part of a long history and many more are buried in the church yard than there are gravestones for - some graves marked with just one name actually contain up to four people, since people have been buried there for hundreds and hundreds of years, grave stones only being introduced recently.

There are also legends of spirits of the deceased buried in the cemetery, two gardeners, father and son, and the former owner of The Bluebell in Yarm.

When you enter the church, directly to the left of the porch is an Anglo-Saxon coffin top that was discovered on-site and inside there are many more historical wonders from all dates.
