Saint AsaphSaint Asaph
(fl. 6th century)
Welsh saint, patron of St Asaph (W. Llanelwy) and its diocese as well as the nearby Llanasa (Flintshire). It has been suggested that Asaph was originally a local saint associated with Llanasa and that his assocation with Llanelwy and the diocese was a 12th-century innovation. A good part of his dossier is formed by traditions associated with St Kentigern from the 12th century onwards, notably Jocelin’s vita of the latter, according to which the church of the see of St Asaph was originally founded by Kentigern, who appointed Asaph, one of his disciples, as his successor.

James fitz Thomas FitzGerald [16th earl of Desmond]FitzGerald (James fitz Thomas) ... 16th earl of Desmond
(d. 1607)
James fitz Thomas FitzGerald, called the súgán (straw-rope) earl of Desmond and styled the 16th (or 15th) earl, was son of Sir Thomas fitz James FitzGerald, who despite being bastardised aspired to the title of earl of Desmond in opposition to his half-brother Gerald and fought for the English Crown. After Gerald’s death, the Crown dissolved the earldom in favour of a Munster plantation, but faced an uprising led in part by Hugh O'Neill, earl of Tyrone. Where James had previously turned to the Crown in the hope of becoming earl of Desmond, he accepted that title from the rebels. In the ensuing years, however, he experienced great difficulty in making his authority felt. In 1601, he was captured and sent to the Tower of London, where he died in c.1607.
