A Murva James b. 26 Jan 1885, Last Residence=Gooding, Gooding Co., ID died Nov. 1973. Her soc. sec. # was assigned in Idaho in 1956. Source: Social Security Death Index.
You can request a copy of her obituary from Random Acts Genealogical Kindness. Go to raogk.org, read guidelines, choose Idaho, choose Gooding Co.
OR maybe the Historical Society does that also.
I checked for everyone in the Western States Marriage and Death records but they weren't there. Successful Searching!
