I am a great grand son of Christian Ade of Gypsum,Kansas. Your account is correct for this family. I am not aware of the Rev. Ade of Buffalo, But the church of Christian Ade at Gypsum was the Temple Society. The Church is still in operation under the name Temple Church. It is an independent Bible Church. Christian and Wife and several children are buried in the Church Cemetery. It would seem that these men must be related due to the Church connection.
