No marriage records found for either of Anna's marriages.
Most likely Grady is Peter Grady b. 1859 Indiana who is 11 pages from Anna's parents in Sterling, Johnson Co. NE 1885.
He doesn't appear on later censuses, so probably died.
An Ancestry Tree has Anna's parents as: Michael Kritner b. 1/3/1826 Baden d. 10/12/1885 Sterling,NE md 3/4/1856 to Nancy Harriet Roy
Nancy Harriet Roy b 10/25/1837 Marion Co. OH to Michael Roy b. 1808 & Eliz. Unk b. 1818.Nancy Harriet d. 12/13/1915 in Rural Adams, Johnson Co. NE & buried Hooker Cem. Gage Co. NE
I did find the marriage record for William Conklin to Elizabeth (Emma) Coon on 7/3/1880 Ida Grove, Ida Co. IA. Wm Conklin s/o Wm Conklin & Julia Cramur; Elizabeth Coon d/o James Coon & Melissa Blake.This info ties to the census as to marriage date for Wm Conklin.I bet the census taker just rolled with that info & assumed Anna was the wife of 20 yrs and since there were 4 children, they were all hers.
Anna L. Conklin died 9/15/1908 in Brookings, SD and is buried at Greenwood Cemetery, Brookings.
You should try to get DC's for Julia B Barnes & Anna L. Conklin.
There are obits for Nancy Harriet Roy Kritner on Findagrave.
