Already, around 160 skeletons have been excavated from the medieval cemetery. Computer scanning of the prehistoric mounds, due to take place at the end of this season, will give a guide to how many people's cremated remains are on the site.
Work on the Roman buildings has been delayed until next year when the site will feature in a special edition of Channel 4's Time Team, presented by Ralf Fiennes, who has visited the site along with Joseph and their sister, film director Sophie.
Cheshire Police are also supporting the project and sharing information with the dig team.
Crime scene investigators use archaeological techniques to remove bodies from shallow graves and Mr Emery's team has also been showing them how the shape of the landscape can help spot potential burial grounds.
Because there is no financial support for the project, much of the funding has been in the form of sponsorship from Daresbury Laboratories and also the Fiennes family, the Duke of Westminster and the Fair family, who own the neighbouring estate.
