I took a look at the death record. She died of moderate cardiac dilatation and generalized tuberculosis. She was born in Iowa. I found a marriage record for a Sarah L Okee born in Iowa married 21 Mar 1900 in Madison, Madison, Nebraska, United States who married a George S Harper who was born in Kansas. Both of them were born in 1873 which matches up with the death record. I couldnt find any local obits. Perhaps they were in the area for medical treatment?
