Notes:
^Scholars have suggested that Tudhaliya I/II was possibly a grandson of the Hittite king Huzziya II; the first Tudhaliya is now known to be the son of Kantuzzili (Bryce 1997, p. 131 suggested Himuili, but the new edition, Bryce 2005, p. 122, indicated Kantuzzili).
^Bryce (1997) does not consider it clear whether Tudhaliya I/II was one king or two (p. 133); the link points to Tudhaliya II. Among those who identify distinct kings Tudhaliya I and Tudhaliya II, Freu (2007) has Kantuzzili—his son Tudhaliya I—his son Hattusili II—his son Tudhaliya II (p. 311).
^The existence of Hattusili II is doubted by many scholars (Bryce 1997, pp. 153–154; Bryce 2005, p. 141). Among those who accept the existence of Hattusili II, Freu (2007), p. 311, has Tudhaliya I—his son Hattusili II—his son Tudhaliya II.
^King (lugal) of Tarhuntassa (Bryce 1997, p. 296); apparently later Great King of Hatti (Bryce 1997, p. 354).
^Nerikkaili married a daughter of Bentesina, king of Amurru (Bryce 1997, p. 294).
^Two daughters of Hattusili III were married to the pharaoh Ramesses II; one was given the Egyptian name Ma(hor)nefrure. Another, Gassuwaliya, married into the royal house of Amurru. Kilushepa was married to a king of Isuwa. A daughter married into the royal family of Babylon. A sister of Tudhaliya IV married Sausgamuwa, king of Amurru after his father Bentesina. From Bryce (1997), pp. 294 and 312.
^Bryce (1997), p. 363. Tudhaliya IV probably married a Babylonian princess, known by her title of Great Princess (dumu.sal gal) (Bryce 1997, pp. 294, 331).
