Morgan was born in a gypsy caravan that stood in a corner of the grounds of the ancient Abbey of Amesbury, halfway between Stonehenge and Woodhenge.
He took a photograph, and from this one photograph came the rediscovery of the Bronze Age site now known as Woodhenge two miles from Stonehenge (Crawford, Air-Photography for Archaeologists 1929).
The site was visited a week later by O.G.S. Crawford, who pronounced it to be the Norwich Woodhenge but it was not until 1935 that it was first excavated, by Grahame Clark.
Alfred Watkins stated that this, now recumbent, standing stone was associated with an alignment originating from Woodhenge.
