Just a update note on Sir Ieuan. ** Please NOTE **  Thanks to Jim  Holloway who so kindly e-mailed me information on Sir Ieuan's marriage to Cecilia dau. of Robert de Clare confirming the Mathew tie to the de Clare family line.  He states: "I thought you'd like to know, from Harleian's "Visitation of Sussex - 1562" that proof exists confirming the Mathew tie to the Clare family, specifically from Sir Jevan ap Griffith's marriage to Robert de Clare's dau., Cecillia.  On page 171 are the Arms of "Richard Mathew of Stansted in Sussex descended out of Glamorganshire".  It is a quarterly of nine, with the 7th quarter being "or", three chevronels engrailed gules", i.e. a gold shield with 3 red chevrons engrailed (CLARE).  This Richard married Elizabeth Campion of Campion's Hall in com. Essex.  The other quarters were: 1. Mathew, 2. Campion, 3. Knotford, 4. Knightley, 5. Mountford, 7. Clare, 9. Skinnerton"".  ""The Genealogical Magazine", reports that the Matthews lineage from Gwaithfoed throught Sir David ap Mathew, knight is recorded and approved as a manuscript in the British Records Office."  "As Richard comes out of our Welsh house, and the British Records Office is a respected authority, this should refute skeptics critical of the Mathews royal ties".  Thank you so much Jim!  I will be updating this area in the near future with the de Clare family information which I have on file.  Additional Ieuan Notes
