Viscount Castlecomer

Sir Christopher Wanderforde, who succeeded poor Strafford as Lord Deputy of Ireland, in April, 1640, was created, between that date and his death, which occurred in December of the same year, Baron Mowbray and Musters, and Viscount Castlecomer. I should be glad to know the date of the patent of his creation, whether Sir Christopher himself ever took up the title, and what became of the title afterwards?
