Lizzie's (your great grandmother) death certificate on Ancestry says she was born 10 Nov 1895. In August 1894, she is named with 3 siblings in a court petition submitted by her uncle, Mike L. Rufty, as guardian, requesting the sale of a parcel of land that she and her siblings own a share of, to be applied toward their care and maintenance. The other children named are Addie, Joseph, and Jay.
None of the children, their father, Rufus, or mother, Ellen are ever named as any race other than white in any census record. I don't see any evidence of Native American or African American ancestry.
I do find it interesting that only four children are named in the petition and the two seen with Ellen in 1900 are not named. Considering their ages and the date on the petition of 1894, it seems pretty clear that the two children living with her were not the children of Rufus Rufty as he was already deceased at the time of their conception.
It is possible that the children were sent to live with their uncle because Ellen was unable to care for them financially and they were later farmed out by their uncle, perhaps when he married, as they aren't with him in 1900.
Life was not easy for women then. If they had no means of support, and no family willing to help, their choices were very limited. She may simply have had no other choice at the time.
