I am the member for the FEAST surname references of the Guild of One-Name Studies based in London (England), and since the 1980s have collected nearly 5,000 world-wide. Unfortunately "advances" in computer technology have reently ruined my original digital files for these people through hardware obsolescence, and although I have paper records they do not contain all of the details which my computer files did.
However, I have been re-creating digital records, one of which was the Yorkshire Feast family with its Baltimore descendants (helped in the late 1980s by Charles Frederick Feast). The English direct descendants have died out, though I believe that non-Feast descendants still exist in the UK. The US seems to have the direct Feast descendants, but I do not have full details.
If anyone would like to co-operate, I would be happy to send PDF files showing the family chart, with additional text giving details and sources of information. I would welcome your corrections and additions. I shall not be available for about ten days, but if you would like to email me I'll send the PDF files as soon as I can.
