has an SSDI that doesn't allow a year range but shows you the county of death.
I used the Mormons first:
1. Verna GARCIA - Birth: 5 Oct 1915State Where Number was Issued: CaliforniaDeath: Jan 1974
2. Verna GARCIA - Birth: 1 Nov 1916State Where Number was Issued: CaliforniaDeath: Jul 1977
3. Verna GARCIA - Birth: 20 May 1918State Where Number was Issued: CaliforniaDeath: Oct 1992
I went to the RW one and tried all 3 years. You have to click on "Advanced" to get the form that specifies birth or death year.
The 1915 one doesn't say. The 1916 one last resided in Lodi, San Joaquin, California. The 1918 one last resided in Montrose, Montrose, Colorado.
http://vitals.rootsweb.com/ca/death/search.cgihttp://vitals.rootsweb.com/ca/death/search.cgi tells me the 1915 one died in Los Angeles County and was born in Wisconson. Now I put on my detective cap. There were not many Hispanic people in Wisconsin in 1915. "Hill" is not a Hispanic surname. Of the three, this one looks the most like your grandmother. She might be one of the other two, or she might not be on the SSDI.
If any of them DO look like your grandmother, you can write to the county in question for a death certificate, which may have her parents' names, but wasn't filled out by her. The cost varies from $5 to $20 by state. For $27, you can write for a copy of her SSN application, which will have her parents' names and was filled out by her when she was alive.
The death index, above, has one Pio Pico, b. 10/12/1909, d. 1974 in Los Angeles county.
