Who is Danelle from Neither Wolf nor Dog: On Forgotten Roads with an Indian Elder and what is their importance?

Danelle is the name of Delvin's wife, who is Wenonah's sister and the granddaughter of Dan. Danelle formally shook Nerburn's hand. Nerburn knew nothing of Dan's history and Danelle until Delvin told him the story. With new information about her parents and Dan, Nerburn saw Danelle from a different point of view. She asked him why he was there with Grover and Dan, and was uncomfortable with his new knowledge about her that Dan had not revealed to him. He told her the story of Wenonah's call and Dan's shoebox full of notes. She asked why didn't he ask an Indian, and Nerburn told Danelle defensively that he's writing for an Indian not about Indians. She abruptly said to Nerburn, "don't blow it mister wasichu".
