• Notes

  Ida familial relations are ambiguous. From their gravestone, Ida is inferred to be a wife of Frank O. Ailo. However, the census records indicate that Frank's wife was Armanda. While Armanda of the censuses has birth dates mostly consistent with Ida's as found on her gravestone, they are not always identical. Ida and Armanda therefore could be separate people. In Frank's 1954 obituary, Aune Johnson is identified as Frank's step daughter. By the time of the notorious murders of 1964, 10 years after Frank's death, Aune is identified as Mrs. Ida Koski's daughter, and Toivo Johnson as her son-in-law.
