No apology needed R21, I know absolutely nothing about the specific in's and out's of researching the archives on these ships.
I am only supposing that Dr. Sinclair and Dr. De bry have done the necessary DD on what they have seen so far from this site. Obviously when they are in a position to excavate the site further the picture will become much clearer.
What little I have read about this fleet and the ships of that era is the propensity for several ships to be named the same thing or confusingly similar to the same name. I suppose they had it down as to how to keep up with them. lol
