morfran is further mentioned in the 13th-century prose tale "the dream of rhonabwy". rachel bromwich notes that a 12th-century poem by cynddelw brydydd mawr contains a reference to an otherwise forgotten early poet named morfran, and suggests a connection with the morfran of "the tale of taliesin" who was the intended recipient of the cauldron of poetic inspiration. scholar caitlin green further suggests a connection with the character called "osfran's son", who is buried at camlann according to the "englynion y beddau" ("stanzas of the graves").
