Thank you gules for your data and have added it to all the bits and pieces about Capt. John Smith's 'Tartar'. No more data has been found about the 'Cups' but I have been sent several accounts of Capt. John Smith's drowning with 3 of his men on 24 March 1797 off the coast of Scilly when his boat, while going from the shore to the 'Lord Mulgrave' of which he was the Commander, was overturned by a violent gust of wind etc. So I have been able to tidy up that part of his life.
Kind regards - Faith
