She was a full sister to Llanarth Meredith ap Braint.
The following article comes from the Welsh Cob Review, Issue 12 from April 1997.
"It is with great sadness that I report the loss of Llanarth Morfydd at the age of 28. Morfydd was foaled at the Llanarth Stud, her dam being Rhosfarch Morwena and the Sire being the late great Llanarth Braint.
She was a wonderful brood mare, producing no fewer than 12 foals in the period from 1971 to 1983, some of which were exported to the U.S.A., Germany etc. Her 1977 filly Llanarth Marged died recently, but Llanarth Stud still have Llanarth Martina who will carry on Morfydds' bloodline.
Morfydd herself was unshown except at Lampeter as a yearling. Llanarth Stud had Flying Comet and Meredith during that time, and so the girls tended to take a back seat!
Her 1986 foal by Rhandir Robert was sold on after being gelded and broken, and has subsequently represented Great Britain in Ireland, Showjumping."
