Find-a-GraveSalome is almost certainly buried in Greenwood Cemetery, Palouse, Washington. Her death notice appeared in the Camas Prairie Chronicle, Cottonwood, Idaho, January 3, 1902, p. 1, and it states that she died at Morrow, Idaho, on Monday, December 30, 1901 of pneumonia, and that the remains were sent to Palouse City for interment.
Her aunt and uncle, Mary Ann and Jared Haskell, and her oldest daughter, Cora McClure are buried next to each other in Greenwood Cemetery, Palouse, Washington. (All three preceded Salome in death.) There is no stone there for Salome, and the cemetery records for that time period were lost in a fire, so there is probably no way to find exactly where she is buried, but it's likely she is buried near them.
When Salome was a baby, her mother, Emeline Rogers, died and the Haskells raised her. Mary Ann Haskell was Emeline's sister.
Salome married Albert Heath on May 20, 1860 in Round Lake, Minnesota. They had five daughters— Cora, Mary, Sylvia, Pearl, and Myrtle.
Samuel N. Haskell was a farmer.
