Here is her obituary from the Modesto Bee, Thursday, 20 June 1985 (forgot to record page number.)
Rinda M. Guttierrez
A service will be held at 11 a.m. Friday at Lakewood Funeral Chapel [Hughson, Calif.] for Rinda M. Guttierrez, 67, who died Monday in Hickman.
Burial will follow at Lakewood Memorial Park. Visitation will be held from 10 a.m. to 8 p.m. today and from 9 a.m. to 11 a.m. Friday at the funeral chapel.
Mrs. Guttierrez was born in Wetumpka, Okla., and lived in Modesto since 1944. She worked at a Tri Valley Growers cannery, retiring in 1983.
She belonged to the Modesto South Congregation of Jehovah's Witnesses.
She leaves four sons, Dale and Tom Guttierrez, both of Alaska, Frank Guttierrez of Colorado and Eddie Guttierrez of Modesto; three daughters, Pauline Hamlin of Ceres, Rinda Weldon of Hickman and Mary Cortani of San Jose; a brother, Raymond Wright of Modesto; 23 grand-children; and 16 great-grand-children.
Ceres is a town of 40,000 located south of Modesto. Hickman is a town of 500 located just east of Modesto. I trust you know the way to San Jose. Your first next step would be to see if you can find any of the named people in an on-line telephone book, I suspect.
If you can find the Funeral home or church in an on-line telephone book, you could try to write to them. They might have records, or someone might know of her family. If they do, they might be willing to forward a note to those people. They would probably not be willing to send you names and addresses of living people, for privacy's sake. If you write, a small donation ($5 or so) would not be out of line, and a stamped, self-addressed envelope would be a must.
I have no relation to Rinda. I live in Stanislaus County. A lady on another forum did me an enormous favor, which I could not repay, so she asked me to do something nice for someone else. I went to the library and read microfilm until I was dizzy.
