Welcome to Just Answer and thanks for contacting us. Do you know approximately when she was born or died? Where she lived? Her husband's name?
Thanks for the additional information. She is also listed in the 1925 Iowa State census for Winneshiek Co., IA as XXXXX XXXXX (age 45) wife of XXXXX XXXXX (49), head of household, son Raymond (14), daughter Helen (11), son Carl (9), son Lyle (7), and daughter Charlotte Lewis (4). Carl (age 9) may be the same child as son Ralph who was listed as 4 5/12 years old in the 1920 Iowa Federal Census.
You can write to the Iowa Department of Public Health for a copy of the death certificate. It is reasonable to state that she died between 1925-1930.
