Analysis of information sources in references of the Wikipedia article "List of rulers of Ammon" in English language version.
Many Ammonite royal names are attested in epigraphic and biblical sources (e.g., Nahash, Hanun, Shanip, Padoel, Amminadab, Hissalel, Baalis).
The names of the known kings of Ammon are (in chronological order) Nahash, Hanun, Shobi, Shanib, Zakur, Yariḥ-Ezer(?), Pudu-Ilu/Buduilu, ʿAmminadab I, Hissal-El, ʿAminadab II, Baalis/Baal-Yashaʿ.
The name of the king of Ammon, šnb, is preserved on a statue, probably representing the king, which was found near Jebel el-Qalʿa, the citadel of Rabbah, modern Amman, the ancient capital of Ammon. This statue bears a damaged inscription on its base, of which the major part may plausibly be restored to read yrḥʿzr [br z]kr br šnb, 'Yerah-ʿazar [son of Za]kkur son of Shanib', thus giving the names of the son and grandson of Shanib (Sanibu).
Sanipu reigned in the time of Tiglath-pileser III (722 BCE). A certain Yarih-azar is mentioned in a statue from the eighth century BCE. He is the son of Zakkur, the son of Sanipu, possibly the same Sanipu mentioned above.
The list of known Ammonite kings is short, so the discovery of a new one is especially important. Some are mentioned in the Bible. In addition to Ba'alis, the Bible also refers to an Ammonite king named Nahash. […] Nahash's son, who succeeded him as king, is identified as Hanun. […] A number of other Ammonite kings are known from cuneiform inscriptions. The total, until the appearance of Barak-el, was nine. Now it is ten.
