In the early 1900s this reached all the way to the Supreme Court. Three sisters of 1/8 Wyandot blood led the charge. They lived at the cemetery in a small shelter to protect it (they were armed) for two years. In 1909, one of the sisters, Lyda Conley, argued her case in the Supreme Court, becoming the first woman (and Native American woman) to do so in the country's history. The court sided with her.
Future legal battles would come however. The courts tended to favor the business interests but local support of the cemetery remained strong. The Wyandot Nation of Kansas incorporated in 1959, further helping the effort to preserve the cemetery. Not surprisingly, the cemetery's addition to the National Register was also controversial. But as stated above, all controversy finally ended in 1998.
