There is a funeral home still operating in Summersville. I do not know the name but the town is very small and if you addressed a letter to Funeral Home, Summersville, MO and zip code the post master will know where it goes. There is a genealogical and historical society in Houston. Here is the address: Texas County, Missouri Genealogical & Historical Society, P.O. Box 12, Houston, MO 65483-0012. It is open on Thursdays from 10 am to 3 pm and is located in the Memorial Bldg., 300 S. Grand, Houston. Hope this helps, Gaycha Mayhew
