Thankfully, Albert Weller accurately recorded most of his sightings, but a few remained unidentified when handed to us. Some I have been able to clarify of my own accord, but some are still outstanding .... so will see if any Forumite can help as we reach them!
However, I defy anyone to differentiate (but no doubt somebody will know of some subtle differences???) between the four sisterships QUEENSGARTH, MONKSGARTH, KNIGHTSGARTH or DUKESGARTH, all of which already feature individually in NEM.
For what it is worth, one of them was seen by Albert sailing from the Tees -undated! Ron
