Surely a typo for Hereford

The grail was, as we all know, taken to Glastonbury
On the dissolution it went to Strata Florida
When Henry VII's men reached mid Wales it was hidden at Nanteos
In the early 70s it was generally held that the owners of Nanteos had placed it in the vaults of Barclay's Bank in Hereford.

No idea what happened to it in the last 30 years.
