Hi, since newspapers charge for obituaries, families don't always submit one. You can send an EMAIL to email@example.com
with her name, death date & place and ask them for her obituary. They will search the newspaper microfilm for one hour for free & reply with what they find.
I did find a Fred and Clara Dusto who were living in Libertyville, Lake Co., IL in 1930. They had been married 2-3 yrs. Fred R., b. MO, abt. 1904, tester telephone co. Clara A., b. MO, 26 yrs old. Fred F., Jr., b. IL, abt. 2 and Ronald L., son, b. IL, 6/12ths.
Clara A. Dusto, 356-12-5731, was b. 30 March 1904 and d. 15 Oct 1991. Her soc. sec # was assigned in IL before 1951. Source: Socail Security Death Index (which anyone can access).
Clara A. Dusto, d. 15 Oct 1991, Mercer Island, age abt. 87 & b. abt. 1904. She lived on Mercer Island [but this might have been where her last benefit check was mailed to instead of residence], 356-12-5731 per death cert #027629. Source: WA Death Index 1940-1996.
You can order a copy of her death cert from the State.
