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. We hope to investigate this further in due course. It is interesting that BLG1952 starts with Gwerystan ap Gwaethford, of Cibwyr, but BPGW2001 starts with Cynfyn ap Gwerstan.
m. Nest (dau of Cadell ap Brochwel Ysgythrog) identified in Griffith's Pedigrees (Golden Grove (p291) & Broom Hall (p331))
1. Cynfyn, King of Powys
  m. Angharad of Deheubarth (dau/heir of Maredudd, Prince of Deheubarth, widow of Llywelyn ap Seisyll, King of Gwynedd)
  A. 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. BPGW2001 suggests she was his 1st wife, mother of Cadwgan, with Haer being his 3rd wife and mother of other issue. We follow Griffith (p392).
  m1. Haer (dau/heir of Gyllyn or Cilyn ap y Blaidd Rhydd, Lord of Gestyn Efionydd)
  i. Maredud / Meredith, Prince of Powys (d 1132-3) HJY
  m1. Hunydd (dau of Eunydd ap Gwernwy, Lord of Dyffryn Clwyd) HJY
  m2. Efa (dau of Blettwrs ap Ednowain Bendew, Lord of Tegiengle (Flint))
  ii. Eva
  m. Llewellyn Aurdochog
  iii.+ other issue - Madog, Rhirid
m2. ?? (dau of Brochwel ap Moelyn of Twr Celyn (Dwrcelyn), Anglesey)
  v. Llywarch
  vi. Cadwgan of Nannau, Prince of Powys (d 1111)
  BLG1952 avoids placing Cadwgan's marriage in order but BPGW2001, 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 BPGW2001 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 ...

  m6. (c1098) Gwenllian (b c1080, dau of Gruffyd ap Cynan, King of Gwynedd)
  j. Madog, Lord of Nannau (b c1100)
  BLG1952 shows Madog as m1. Jane m2. Efa but BPGW2001 & Griffith (p200) show the marriages as follows.
  m1. Efa or Eva (dau/heir of Madog ap Philip ab Uchtryd, Lord of Cyfeuilog)

  (j) Gwenhwyfar
  BPGW2001 mentions this daughter Gwenhwyfar, noting that she did marry (husband not named), but also shows two Gwenhwyfars in later generations who both married John ab Einion of Efionydd (see above ##). Identifying her as this Gwenhwyfar is done by BP1934 (Newborough) which we provisionally follow.
