A number of changes have been made to this profile since she was added to Geni. Unless there is new information, backed up by reliable sources, all that we know about her is that, according to Friedlander family oral history, she was connected with the Gaon of Vilna somehow.
Recently, Geni members and curators have added the name Pesa, attached her to the Vilna Gaon as a child, and have suggested that she is Peisa Bassia Vilner, of Disna, wife of Tzvi Hirsh Donchin. This daughter's marriage and descendants are discussed in Chaim Freedman's book on the genealogy of the Vilna Gaon, pages 104-125.
Please discuss here if you want to argue for the changes that have been made. For the time being, I have undone the changes to match Freedman's book. If he has made further discoveries, please update sources and the Overview and discuss here.
