I did some searches this morning, which will help. I first went to the 1925 Iowa State census and looked up the Benscoter family. I found on image 104 the family and Ethel M was there with the family as single. I then checked the Family trees for Fay Benscoter family, and one of the Public Trees by one Thomas Hagar of Lees Summimit Mo. showed Ethel Maud with two husbands. an Edward Speisser, with no dates, and James Staley with a birthdate of 20 Jan 1900 no other dates. I then checked another and there found the information you were looking for, under James Staley as spouse listed two children, one living, and the other Wendell Staley with birth and death dates

Ethel Maud Benscoterb 29 may 1900 Olivet Iowa, died 10 June 1981 Seminole Oklahoma (this according to the Public Tree site) earlier I has tried to see if James H. Staley was listed on Find-a-Grave. I could not recall the birthdate at the time , but found one that I thought was close, then I reread what I had sent to you before, and found that birthdate from his 1917/18 draft card
Find-a=grave: James H Staley Jan 26 1899died Jan 29 1962 Seminole Co. Oklahoma
He is evidenly listed on the 1930 Iowa census Newton Marion Co. James Staley31 marr#1atage 27 Margaret22 marr31atage 18 ( It could be that this Margaret, and the Margjorie listed on the Marion County records are the same person, a lot of the Iowa Records I find have errors. because of the condition they are in.the ones who read them often see things differently )
