I  cannot access the Goucher article cited by Ray, but there is another by her: https://www.jstor.org/stable/25130565 in African Arch. Review 1993.  I am hoping to put together a first draft of an article in reply next week.  I will need to pass this around for comment.  Such an article was the solution that emerged from discussions at Coalbrookdale Museum last weekend.

Ray: can you e-mail me on peterkingiron@blueyonder.co.uk so that I have your contact details.  I will want to make use of what you have found out about the Abby’s voyage, with due acknowledgement to you.
