|Has Note=The NLW finding aid for Cwrtmawr manuscripts suggests that [[Aberystwyth National Library of Wales Cwrtmawr MS 314-315D|MS Cwrtmawr 314-315D]] shares a source with this text, or alternatively that it may be a copy of this text. [[Lewis (1925, 1958, 1967)]] claims that this text, and the edition in ''Cymru Fu'' (1862), have as their source one of the two copies of the ''Ystori'' in the British Library - specifically, the earlier of the two texts, rather than the later copy in Owen Myfyr's handwriting.
