Is Saxons' Lowe - or should that be Saxon's Lowe - a prehistoric round barrow? Or maybe it's the grave of a Saxon King from the nearby Bury Bank? Or is it just a natural bump (mind you, it is scheduled as an ancient monument, according to the Magic map).

The 'Alternative Approaches to Folklore' bibliography by Jeremy Harte has a reference for another story: http://www.hoap.co.uk/aatf1.rtf.
Chris Fletcher, in a letter to Mercian Mysteries 17: 37 (1993) described how the barrow called Saxons Lowe on Tittensor Chase was visited by a will o' the wisp.
