I'm trying to locate information (especially an obit with a date and place of death) for Wilhelmina ("Minnie") MALCHOW, who is listed in the 1920 Federal Census in Benton County, WA. At the time, she was 78 years of age and living with her daughter-in-law, Anna MALCHOW (the widow of Minnie's son, William F. MALCHOW) and Anna's children: Lily, Esther, Walter, and Herbert MALCHOW.
Her son William F. MALCHOW (22 Jan 1874/75 - 11 Oct 1919) is buried at Riverview Heights Cemetery, and I'm wondering if Minnie might be buried there, too.
Minnie was born Caroline Wilhelmine HANDRICH on 8 Feb 1841 at Mewegen, Kreis Randow, Pommern, the first child of Johann Friedrich Wilhelm HANDRICH and Marie Dorothea ROHDE. She married Wilhelm Malchow (born 1839 in Mewegen) in 1862 and emigrated to the U.S. that same year, settling first in Wisconsin.
Any information or referrals to other sources will be appreciated. There is much additional information about her family to share with interested descendants.
