An Anna Louise Pickett b. 16 Dec 1856, NY died 18 May 1947, Glenn Co., CA. Father's Surname=Stratmoer. Source: CA Death Index 1940-97, www.ancestry.com.
I didn't find anything on Hiram but I bet he died in Glenn Co. I'd do a search for the Glenn County Genealogy Society and if they do research, they can look him up in the CA Death Index. Successful Searching!
