Sallie was born July 13, 1888 in Lehighton to Oliver or Alvia Whiteman and Emma Arner. Oliver remarried in 1900 after the death of Emma to Mary Hoffman. Sallie is in the 1900 census under the name Sadie which was sometimes interchangeable with Sarah and Sally. This is mostly information based on what someone posted on Ancestry and from what I've seen seems reliable. The record of her second marriage does list Alvia Whiteman and Emma Arner as her parents. However, I suggest getting Sallie's death certificate and obit just to make sure. She died on Feb 18, 1968 in Washington County, MD under the name Barger.
