Question: Did Ida's father have more than one child? Passage 1:The Anglo-Saxon Chronicle indicates that Ida's reign began in 547, and records him as the son of Eoppa, grandson of Esa, and great-grandson of Ingwy. Likewise, the Historia Brittonum calls him as the son of Eoppa and the first king of Berneich or Bernicia. The Anglo-Saxon Chronicle elaborates that he ruled for twelve years and built the Bernician capital of Bamburgh Castle. Later, however, the Chronicle confuses his territory with the later Northumbria, saying that Ælla, historically a king of Deira rather than Bernicia, succeeded him as king after his death. Northumbria did not exist until the union of Bernicia with the kingdom of Deira; this happened for the first time under Ida's grandson Æthelfrith. The genealogies of the Anglo-Saxon kings attached to some manuscripts of the Historia Brittonum give more information on Ida and his family; the text names Ida's "one queen" as Bearnoch and indicates that he had twelve sons, naming among them Adda, Æthelric, Theodric, Eadric, Theodhere, Osmere and Ealric. Several of these are listed as kings. One of them, Theodric, is noted for fighting against a Brittonic coalition led by Urien Rheged and his sons. The genealogical preface to Chronicon ex chronicis names six sons, Adda, Bealric, Theodric, Ethelric, Osmere, and Theodhere, born to his wife and six born to concubines, Ocga, Alric, Ecca, Oswald, Sogor and Sogothere. Ida's successor, Glappa, does not appear among his sons in any of the early sources. Ida's descendants would rule Bernicia and later Northumbria.

 Passage 3:Helped by his association with The Guardian, Cannon was able to contribute more substantial articles to the Los Angeles Times and the Chicago Sun-Times, and to underground magazines such as Creem. He wrote the 1970 documentary film London Rock, focusing on the UK's counterculture movement. He recalls that, together with Rolling Stone journalists David Dalton and Jonathan Cott, he joined Granada Television documentary-makers such as Jo Durden-Smith, John Sheppard and Michael Darlow in devising "prime-time networked shows designed as anthems of the revolution".

He also directed the film of Frank Zappa's performance at the 1970 Palermo Pop Festival, for RAI, Italy's national public broadcaster.
