Lillian Frances Jacobs (Wilanski) - factually-incorrect information

Information this page is factually incorrect. I'm one of Lillian Frances Jacobs' Maternal grandsons and cay for a fact that neither Ruth Cass or Sybil Lang were her half sisters. All 3 were born of the same mother and father making them full sisters.
Unfortunately I'm not able to edit the page or I'd make the correction. Should anyone read this and have to make the change, please do so.
