No one by that name on any list I've seen. Sequoyah told people he had twenty children, but that only ten survived. Starr lists Teesee, George, Polly, Richard, E-ya-gu,(Ayoka), Oo-loo-tsa, and Gu--y-ne-ki. Sally Waters Guess is on the Old Settler with two more, Lucinda and Susie. They were all born before 1840 and all died before the Dawes.
According to Nancy Blackbird's Eastern app she was born in 1860, the daughter of a man named George Guess, a different man from Sequoyah and probably unrelated. Sequoyah's son George had a daughter named Nancy but she is not this woman - that Nancy died in 1879. Nancy Blackbird was not an Old Settler and the Guess family all were. Nancy Blackbird's mother and grandparents all had only Cherokee names and people knew Nancy by a Cherokee name. Nancy was born in 1860. She is not listed as anyone's heir on the Old Settler Payroll.
I don't think anyone knows who Sallie Water's parents were. That's one of Hicks' inventions.
