Bereh Halseth in the Washington, Select Death Certificates, 1907-1960 Name: Bereh Halseth [Bereh Rusten] Gender: Female Marital Status: Married Age: 61 Estimated birth year: abt 1858 Death Date: 29 Apr 1919 Death Place: Keyport, Kitsap, Washington Father: John Knudsen Rusten Mother: Spouse: Ludvig Theodor Halseth FHL Film Number: 1992539 Reference ID: 127
The only connection I can see between this person and the Rusten mentioned in the death record for Berit Halseth is this reference to Rissa in the birth location

Some information can be gleaned from an unrelated 2007 post from Norway Heritage
