[1]  This family is a junior cadet of the ruling family of Meirionydd and descended from Meirion, the youngest son of Cunedda
[2] Einion ap Seisyllt of Meirionydd fell into disfavor with Cynan ap Owain Gwynedd after the latter's death in 1170.  He sought the protection of Owain Cyfeiliog king of Powys and married his son to that king's daughter.  Thereafter his lands, which bordered Cyfeiliog (and were only a small part of the cantref of Meirionydd), were detached from the kingdom of Gwynedd and became a part of Powys
[3] The medieval pedigrees make Sian a daughter of Einion ap Seisyllt, but that chronology fails by a full generation.  She may have been his sister.
[4] Most pedigrees seem to date Einion 60 years later by omitting one pair of the repeating names "Tudor ap Gronwy"
[5]  Marged is cited as a daughter of Dafydd Lloyd, the bard of Mathafern, who is incorrectly cited as "ap Llewelyn ap Gruffudd".  That construction incorrectly omits an earlier Dafydd Lloyd who was the grandfather of the bard.  The latter was alive in 1485, but too old to join the battle of Bosworth, when he predicted the victory of Henry Tudor over Richard III.  Mathafarn was a town in Cynllaith named after an earlier manor of that name erected by an ancestor of Dafydd Lloyd who acquired the land via marriage.  Lloyd was NOT a surname; direct descendents of the bard adopted the surname PUGH after Dafydd's grandson Huw.  The name is an elided "ap Huw".  Lloyd was simply a nickname meaning "gray"
