There is some confusion in a few trees regarding Lucinda/Cinderella. I think Cinderella is the daughter of Robert and Susan a.k.a. Sindirilla Duston from the 1870 census. She was born in 1863. A few people have Silas as Robert's brother, but all the records show to me that Silas is Robert's son, and Sindirilla/Cinderalla's brother. I can't find an actual record that shows Silas having a daughter named Lucinda, only a few trees that seem to show that, but I think it is an error otherwise there would likely be a census showing that somewhere and I have yet to find it. I do see Silas having other children, but not a Lucinda.
I think Cinderella has gone by several names. I have seen her as Lucinda and even Mary in on census.
