Johan, Albert, Bertha, and Herman are buried in Offerle, Kansas at the Lutheran church there. Offerle is a very small farming town in western Kansas. I think Johan and Ida might have lived in Illinois before moving to Kansas. I hope this helps! This information comes from a publication of the Lutheran church in Kansas that they attended. Please email me or post any additional information you may have about Johan and Louisa's origins. Thanks!
