Roberta, Death records do not show any Nora SHUMATE death in Parker County in 1982.The records also do not show a "Nora" of any last name dying 1982 in Parker County.There is no listing for the death of Nora SHUMATE in Texas during the period 1964 to 1998.There is one Nora Osburn McGraw listed but she died 1979 in Harris County Texas.Since burials are recorded by the married name, she obviously was not married to "SHUMATE" at the time of her death.
There are a number of reasons she might not appear.(1) She died outside the State of Texas.(2) She remarried before her death and is buried under her new surname. (3) She divorced and legally returned to her maiden name.(4) She died without anyone knowing her name and she is buried as a "Jane Doe".
