Thank you Kaysii
That is a very useful site, which I had not come across before, and have been able to pinpoint the area much more efficiently.
Have contacted ( by e-mail ) Happisburg, Cromer and the East coast Marine Heritage site, and will fill in info on here, when I hopefully get it.
This is the second ancestral wreck I have chased on this coast, other was the Brig 'Transfer' on the Scroby Sands, but after several negative reports,- found that all crew - after five hours in an open long boat (and gale conditions) had been picked up by the 'Beamont' and landed safely ( at the time after taking the crew aboard the 'Beamont' had to cut the long boat free, due to heavy weather.
Best
