David Unaipon was born at Raukkan, on the southern bank of Lake Alexandrina in South Australia on 28 September 1872. Raukkan means "ancient place" in the indigenous language of the area, Ngarrindjeri; the anglicized name for the place, Point McLeay (named for the British explorer Charles Sturt's second-in-command) often appears on the maps of the area. Point McLeay was the site chosen for a mission set up in 1860 by the Aborigines' Friends' Association (AFA), an interdenominational group, although it was dominated by Protestant clergymen, which had formed a year earlier. Unaipon's father, James Ngunaitponi (the name Unaipon is also an Anglicization) was the first Aboriginal convert, arriving at the mission from Wellington on the eastern bank of the lake by boat in 1864. In 1866 he married Nymbulda, the daughter of Pullum, the rupulle, or president of the Karatindjeri tribe. It was the first Christian ceremony held at the mission. David Unaipon...
