On 27 July 1866 Unaipon married Nymbulda, the daughter of Pullum (King Peter) who was the Rupelle[a] (misinterpreted as "King" by colonists) of the Ramindjeri. The Rev George Taplin assumed that the position of Rupelle was hereditary and widely promoted Nymbulda as a queen, believing that a missionary related to royalty would be more influential in converting the Ngarrindjeri. The Rupelle was in fact elected by the Indigenous Tendi (government) and conferred no additional status to his family.[2][3][b]

^The various clans of the Ngarrindjeri are led by elders who also represent their clans in the Ngarrindjeri Tendi (council or government). The Rupelle is the elder chosen to preside over the Tendi only and has no personal authority over the Ngarrindjeri.
^The only source for the name Nymbulda is George Taplin. The Yaraldi genealogy compiled by Ronald Berndt names her as Nymberindjeri with Nymbulda being her father's first wife and there was also another of that name married to another relative. It can not be ruled out that she was known by both names.
