I've come across a Huw ap William (or Huw Williams or Hugh Williams) and can't seem to find anything apart from his wife and decedents and wonder if anyone else could help. Ancient & Modern Denbigh (John Williams) has: "Dr John Dolben, Archbishop of York; and it's worth observing that his mother was the daughter of Capt Williams of Cochwillian, and sister of Archbishop Williams." National library of wales (http://yba.llgc.org.uk/en/s-DOLB-EN0-1500.html) has: "daughter of captain Hugh Williams of Wig , a soldier of fortune ( A.P.C. , 1621-3 , 368), and of Elizabeth , sister of archbishop John Williams" Annals and Antiquities of the Counties and County Families of Wales (Thomas Nicholas) p363 has: "Dorothy, who m Capt Hugh Williams of Weeg." The baronetage of England (William Betham) p279: "Edmund had also 2 daughters, Dorothy, the wife of Captain Hugh Williams of Weeg; secondly of sir ___ Powl, Knt" Observations on the Snowdon Mountains (William Williams) p182: "Dorothy, the wife of Captin Hugh Williams of weeg, killed in Flanders"
