Isobel Wolmby

Isobel Wolmby or Kornomnayuh Telpo’ana Gothachalkenin, (1917 – 26 May 1989) was an Australian indigenous culture informant.

Her mother, Yukwainten Wontuttin Peeoont Koowaytairun Marpoondin, was one of the eight wives of Billy Wildfellow and she had sixteen siblings or half-siblings.

[2] Mackenzie's punishments were described as "harsh, unorthodox, and arbitrary – they included the use of banishment, corporal punishment, including flogging and beating, use of his fists, use of the 'electro magnet', binding the mouth to stop verbal abuse and swearing.

The two of them attached themselves to the "Old Arraman Mob" and she gathered tales from some of the last local aboriginal people who were not living in a mission or similar.

Victor was to become recognised as a leader and Isobel became a source of the group's verbal history.
