Hi Sheena,
You’ve probably already come across this but one of the Lecturers in the History department of Keele University, one Robin Studd, appears to be something of a “templars in Staffs” expert. Two of his papers include:
“A Templar Colony in North Staffordshire: Keele before the Sneyds”, Essays on the History of Keele, ed. C.J.Harrison (1986), pp.5-21
and
“From Preceptor to Prisoner of the Church; Ralph Tanet of Keele and the Last of the Templars”, Staffordshire Studies 8 (1996), pp.36-49
Also I know this isn’t exactly on-topic but this link [url:dlygrrzz]http://www.pglstaffordshire.co.uk/history.asp[/url] mentions a history of Freemasonary in Staffs by F A Cotton which may give clues to previous Templar activities. Interestingly Dr Plot is mentioned here, forming a link to the other part of your question (the lunar standstill).
Cheers,
Simon
