The future biographer of Dr. Caesar Clement, English Catholic exile and nephew of Margaret Clement, prioress of the convent of St. Ursula at Louvain, will have a nugget of information in the evidence that Clement was one of the chaplains in the Archduke Albert's chapel royal from at least 1602 through 1618, probably longer, a fact not known to the compiler of the DNB account, who mentions only that he was chaplain general to the Spanish army and dean of St. Gudule's in Brussels.
