Hi, Missouri has started putting death records online. They have an index from 1910 to 1955 and from 1910 to 1920 they have the actual death certificate images online. http://www.sos.mo.gov/archives/resources/deathcertificates/ So, if your Butler Co., families traveled west, you might want to check this out. I got lucky and found my gg-grandpa's death certificate. I had no idea where he died or was buried! I knew he was in Missouri and that was all. Happy Hunting, Norma
