Thanks for your efforts. I found a 1920 census record showing Isabella and Leroy Richardson living in Columbia, Gibson County. But couldn't find a 1930 census record for Indiana.They could have died in that span. It seems that Leroy and Isabella crossed the state line and married in Wabash County, Illinois (5-18-1893). It would seem that at least one of them would have died in Gibson County in 1920 or later. What is your data source? Online subscriptions or books? Thanks again.
