                                 ANGHARAD, HEIRESS OF MOSTYN
                                          By Darrell Wolcott
         In 1925, Llewelyn Vaughan (the 3rd Baron of Mostyn) and T. Allen Glenn compiled a History of the Family of Mostyn of Mostyn.  According to that work, the land upon which now stands Mostyn Hall in Flintshire was acquired in the early 1400's by the marriage of Ieuan Fychan ap Ieuan ap Adda ap Iorwerth Ddu ap Ednyfed Gam of Pengwern and Angharad, daughter of Hywel ap Tudor ap Ithel Fychan of Mostyn.  That the land was formerly owned by that Hywel ap Tudor is not in doubt; what we question is whether this Angharad was, in fact, his daughter.
         Let us begin by sketching the chronological timeline of these families.  Hywel ap Tudor married Lleuci ferch Rhys ap Robert ap Gruffudd ap Sir Hywel ap Gruffudd ap Ednyfed Fychan[1]; this lady would occur c. 1355.  His father Tudor married Erddylad ferch Madog ap Llewelyn ap Griffri ap Cadwgan ap Meilyr ap Elidyr ap Rhys Sais II[2]; she would have been born c. 1330.  Extant deed records show Tudor ap Ithel Fychan acquired several tracts of land in the mid 1300's[3]; we would assign his birth near 1315 and his son, Hywel, to c. 1345.  Hywel inherited the bulk of his father's land and became a supporter of Owain Glendwr in 1403.  To that cause, he was joined by his son Ithel, a man yet in his 20's.  That he also had a daughter named Angharad is certain; in 1388 he deeded certain of his lands over to her[4].  The following chart shows the probable timeline:
              1285  Ithel Fychan              1260  Ednyfed Gam
                             l                                       l
                1315   Tudor                   1295  Iorwerth Ddu
                             l                                       l
                 1345  Hywel                      1330  Adda
           __________l________                        l
           l                                l                        l
1375  Ithel             1373  Angharad             Ieuan  1360 ob 1448
                                                         Ieuan Fychan  1390 
        The family on the left was descended from Edwin of Tegeingl[5] and had been landholders there for several hundred years.  The family on the right, which inherited Mostyn from an heiress of the Tegeingl family, was descended from Tudor Trevor[6].  To demonstrate the absurdity of the claimed marriage between Ieuan Fychan and the Angharad in this chart, lets follow his descendants for a few generations.
        The son of Ieuan Fychan was Hywel "dun stag" who married Margaret ferch Gruffudd[7], heiress of Gloddiath and born c. 1440.  Their son, Richard, married Catherine daughter of Thomas Salusbury, Jr, of Lleweni and died in 1539[8].  Their son, Thomas ap Richard, was the first of the line to adopt the surname Mostyn.  He died in 1558.  Thus:
  1390  Ieuan Fychan=====Angharad of Mostyn
                     1425  Hywel====Margaret of Gloddiath  1425
                           1457  Richard*===Catherine Salusbury  1465
                              1490  Thomas Mostyn, ob 1558
                *Joined Henry Tudor at Bosworth in 1485; died 1539
         Quite clearly, the heiress of Mostyn named Angharad was NOT the daughter to whom Hywel ap Tudor granted some lands in 1388; that Angharad would have been nearly 20 years old when Ieuan Fychan was born, even assuming her father gave her the lands when she was but 15 years old.
          Several medieval pedigree manuscripts[9] cite the marriage of "Angharad ferch Hywel ap Tudor" with Ieuan Fychan.  Other manuscripts of that period[10] also say a lady of that name married Edmund, son of William Stanley.  Only a single manuscript[11], written later than the others, says it was the same lady who made both marriages.  In his History of Powys Fadog, J.Y.W. Lloyd[12] claims Angharad ferch Hywel married Ieuan Fychan as her first husband and left Mostyn to her son by that marriage, Hywel ap Ieuan Fychan.  Her second marriage, according to Lloyd, was to Edward Stanley by whom she had a single son William.  That son received Llaneurgain and Llys from his mother.
        Dr R. Rees Davies, in a 1969 paper presented to the Honourable Society of Cymmrodorion in London (published in the 1968 Transactions of that society as "Owain Glyn Dwr and the Welsh Squirearchy") describes the 1388 grant from Hywel ap Tudor to his daughter Angharad in these words: Y Hen Hall in Mostyn was "mentioned in a list of his property with which he invested his daughter, Angharad, in 1388 thereby effectively disinheriting his (? illigitimate) son Ithel". We have not seen this document and suspect Dr Davies actually is speaking of two different things:  a 1388 grant of some lands to his daughter Angharad, and a later list of lands inherited by an Angharad which included Mostyn...the assumption they were the same lady being his.  The idea that his son Ithel was disinherited is, we think, no more than a by-product of the first incorrect assumption.
         We think the only marriage of Angharad ferch Hywel was to Edmund Stanley when she was about 15 years old.  Her father provided a dower for her consisting of the Llaneurgain and Llys manors which later went to her son, William Stanley.  The bulk of his lands, including Mostyn, were left to his only son, Ithel.  And it was Ithel who had no issue save a daughter named Angharad that was father to the "heiress of Mostyn".  This Angharad, born c. 1405, married Ieuan Fychan of Pengwern and carried Mostyn to their son, Hywel ap Ieuan Fychan.  Thus:
                                       1315  Tudor
                                    1345  Hywel
               l                                                    l
  1373  Angharad                               1375  Ithel
               =                                                  l                     1390
1360  Edmund Stanley                    1405  Angharad===Ieuan Fychan
               l                                                            l
           William IV                                     1425  Hywel
      (Llaneurgain)                                             (Mostyn)
        In his charts for this family[13], Peter Bartrum includes a single Angharad as the daughter of Hywel ap Tudor and makes Ithel ap Hywel childless.  But in his generational dating system, he makes this lady 2 generations younger than her "father" and a full generation younger than a sister.  For whatever reasons, Bartrum did not date Ithel ap Hywel at all.  While this dating of Angharad (to c. 1405) is consistent with the marriage with Ieuan Fychan, it does not explain how she could also have been living in 1388 and old enough on that date to receive land of her own.
               The Mostyn family papers now held at Bangor University show the family has for centuries misidentified the heiress, confusing a same-named aunt with her niece.  Their error has been incorporated into the 16th century pedigree manuscripts and never questioned since genealogists of that era did not consider chronological stability in pedigrees they cast.  If you choose to believe one of the wealthiest men in Flintshire[14] gave all his lands (at least 19 years before his death[15]) to a teenage daughter who later married a man almost 20 years younger than herself (when she was near age 50), then you probably also invested in some ocean-front property in Arizona. We aren't buying either.  Angharad the heiress of Mostyn was the grand-daughter of Hywel ap Tudor.

[5] The descent from Edwin was through Maredudd ap Uchdryd, but not Uchdryd ap Edwin.  The Uchdryd in the pedigree occurs c. 1085 and was probably a grandson of Edwin, most likely a son of Uchdryd ap Edwin. See our paper on Maredudd ap Uchdryd at the link below:
