"Tree based on the relative chronology of sound changes"  Li (2009) considers the second tree (the one containing the Taivoan–Makatao group) to be the somewhat more likely one. Lee (2015) regards that, when Siraya was a lingua franca among at least eight indigenous communities in southwestern Taiwan plain, Taivoan people from Tevorangh, who has been proved to have their own language in "De Dagregisters van het Kasteel Zeelandia", might still need the translation service from Wanli, a neighbor community that shared common hunting field and also a militarily alliance with Tevorangh. The Siraya language entered the historical record in the early 17th century when traders from the Dutch East India Company, expelled from mainland China and Chinese waters, set up a stronghold on Taiwan at Fort Zeelandia, which was in the Siraya-speaking area. During the period of Dutch rule in Taiwan, Calvinist missionaries used Siraya and Babuza (also known as "Favorlang") as contact languages. A translation of the Gospel of St. Matthew into Siraya (174 pages of Siraya and Dutch text, Gravius 1661) and a catechism in Siraya (288 pages of Siraya and Dutch text, Gravius 1662) were published, and have been subsequently republished. The Dutch colony was driven out in 1661 by Ming loyalist refugees from China, and Taiwan was subsequently incorporated into the Qing Empire. During the period of Qing Dynasty rule, use of Siraya receded, but some Siraya language materials survive in the form of Siraya land contracts with Chinese translations, known as the Sinckan Manuscripts. The last records were lists of words made in the early 19th century. The Tainan Ping-pu Siraya Association is compiling the first modern-day Siraya glossary. Publication is scheduled for November 2008. The phonological system of Siraya is speculated by Adelaar (1997) to have the following phonemes. Consonants (18-20 total) Vowels (7 total)  Diphthongs (6 total)  Palatalization also occurs in many words. Siraya auxiliaries constitute an open class and are placed at the head of the verb phrase (Adelaar 1997). The Siraya personal pronouns below are from Adelaar (1997).
