Wales 5: Lords of Nannau, Kings/Princes/Lords of Powys
Gwerstan or Gwerystan >Gwerystan is shown in Griffith's Pedigrees as son of Gwaithfoed Fawr, normally called Lord of Powys but sometimes called Lord of Cibwyr in Gwent, by Morfydd, dau/coheir of Ynyr ddu, King of Gwent. However, this parentage appears to be disputed by those who think that he was possibly a Saxon whose name may originally have been something like Werestan. BLG1952 starts with Gwerystan ap Gwaethford, of Cibwyr, but BLGW2001 starts with Cynfyn ap Gwerstan.

Da31. Cynfyn, King of Powys
m Angharad of Deheubarth dau/heir of Maredudd, Prince of Deheubarth, widow of Llywelyn ap Seisyll, King of Gwynedd
Da30 Bleddyn, King of Gwynedd, Prince of Powys b c1025, d 1075 §W§ There is some disagreement on the order of Bleddyn's marriages. BLG1952 identifies only his 2nd wife, dau of Brochwel ap Moelwyn, showing her as mother of Llywarch, Cadgan, Hunydd & Gwenllian. BLGW2001 suggests she was his 1st wife, mother of Cadwgan, with Haer being his 3rd wife and mother of other issue. We follow Griffith p392.

Da29-6 Cadwgan of Nannau, Prince of Powys d 1111 BLG1952 avoids placing Cadwgan's marriage in order but BLGW2001, whilst noting that the order is uncertain, follows that given in 'Peniorth'. Griffith p392 shows only 4 marriages: Gwennllian dau of Gruffydd, Frances Pigot, Gwennlian dau of Owen, and Elliw. On this we follow BLGW2001 which does not name the 1st wife but reports that she is sometimes "called in error Iwerydd, dau of Edwin ap Gronw". Griffith identifies the mother of Owen, Goronwy & Llewelyn and hence possibly Cadwgan's 1st wife as ...
