Checked the Cambrian Article - does refer to John not David Hosea Jones but clearly an error. Very little in the article.
Checked the Coroner's records and took a copy of the inquest into David's death. It includes 2 descriptions from witnesses. They appear beautifully written by the Clerk recording the statements but, unfortunately, are virtually imposible to read - and I was reading the originals!!
Overall, they don't add to much, if anything, to David's personal details.
Can send images if you would like - need your e.mail address via PM.
