It looks like Lac Courte Oreilles has some of the lowest blood quantum requirements of all Wisconsin Tribal Nations for enrollment. They operate under Lineal Descent, with no specific blood amount required, but must be able to trace to an ancestor from the 1940 census for LCO as listed below.
Ms. Siobhan Marks being 1/32 and far removed from an ancestor on the LCO tribal census roll and is therefore ineligible for enrollment at Lac Courte Oreilles, and labels herself a "Descendant."
So it would be illegal for her to manufacture, market, or sell her Grandmother's Strap Dresses or any others items, as Native American made under the Indian Arts and Crafts Act of 1990 posted link below also.
Under the Act, an Indian is defined as a member of any federally or officially State recognized tribe of the United States, or an individual certified as an Indian artisan by an Indian tribe.
