Hi Robert.
Found your search for John David Teubner while conducting my own search of him. If you are still looking for information, he is my Great, Great Grandfather through Tobitha Angeline (my great grandmother) - Clarissa Jane Bozman (my grandmother) - Elizabeth Bolen Minton (my mother). The link for his gravesite is: https://www.findagrave.com/memorial/48396186/john-david-teubner (Find A Grave - Topeka Cemetery Topeka, Shawnee County, Kansas, USA - memorial ID 48396186). That makes us distant cousins.
