Hi Jo... I see a contridictory problem in your facts. You state that the marriage application and the license yourgrandmother, Ida Mae Koach, was 23 years old in 1903. That would make her born in 1880, not 1887 as you state on the death cert & funeral records. One or the other is incorrect. If she was born in 1880 in Moss Co, KS, you might want to check the 1885 KS Agricultural Census records for Moss County. Another avenue of search "might" be the cemetery records. I found the full name of my g.grandfather in Fairlawn Cemetery in Stillwater, OK. And, a third one, which I'm sure you've already tried, is to search for the name COOK since it was pronounced like Cook. Just some suggestions. Lois in CA
