According to 1920 census John W. Day was born in 1855 in Kentucky. He was married to Didama Day b. 1846 Ohio. Here's the timeline that I know:
1915 Fort Scott, Kansas John W. Day 60 & wife Didana Day 76
1916 Chanute, Kansas, Pastor, Christian Volunteer Church
1919 Miami, Oklahoma, Commander J. W. Day of the Volunteer Missionary Church
1920 Miami, Oklahoma, John W. Day 65 Minister, Didama Day 74
1927 Iola, Kansas, John W. Day & Didama

Anyone know about Christian Volunteer Church? How long were John W. Day/Didama Day married? Did they have children? When/where did Didama and John W. Day die?
