Major Lancelot Sumner[1] was born in 1948 on Point McLeay mission on the shore of Lake Alexandrina in South Australia,[2] one of 12 children.
The family moved to Millicent in the South East of the state, but after his parents split up, he and several brothers were placed in a boys' home in Adelaide.
[3] His father, Colin Rex Sumner, was buried in an unmarked grave in the West Terrace Cemetery in Adelaide after being allegedly murdered in a brawl in the north of the state.
Moogy has been investigating how to find his father's remains and re-inter them at Long Point (aka Dapung Talkinjeri), where he was born.
[2] In 2010, he began the "Ringbalin Murrundi" Rover Spirit project, which relit the ceremonial fires along ancient Aboriginal trade routes of the Darling and Murray Rivers.
[12] The 2024 event included performances by the Tal Kin Jeri dancers; cultural workshops in basket-weaving, yidaki, and carving clubs and clap-sticks; traditional ceremonies; and a marketplace.
[22][23] In 2018, Sumner stood for the Australian Greens in a by-election in the Division of Mayo, as they were the party which had the strongest policies to protect the Murray.
[1] A previous resident of Millicent in the South East of the state,[17] Sumner lives and works in Adelaide and at Camp Coorong.
