Siobhan Marks or Zeegwun Noodinese, is a lineal descendant of the Lac Courte Oreilles Band of Lake Superior Chippewa (LCO). She is Eagle Clan and Midewiwin, and was born and raised in Northern Wisconsin. Her Ojibwe grandmothers were from Rice Lake, LCO, and Flambeau, and they attended Catholic Mission Schools as children.

Siobhan is a Water Walker and Water Protector who advocates for clean water, sacred spaces, Native women, and all living things. She has been a part of many Water Walks, rallies, and marches. She was also at Standing Rock, alongside her Midewiwin relatives, taking part in tobacco and water ceremonies. Siobhan has researched the original dress of Indigenous women — nearly erased through assimilation and Indian Residential/Boarding Schools — and has shared this knowledge at universities, museums, and tribal Nations across the country. In 2019, she recorded a TEDxTalk on this important work.

She and her partner, Marin Webster Denning, share two grown children and four step-children.
