I have found Guardianship papers (1864) for William Henry Mesenbring(k) heir of Heinrich Mesenbring(k) in the Lafayette County MO Probate Court Records. The guardian is Henry Dedeke whose wife was Doro Mesenbrink. An Inventory of the Estate is among the papers. A letter from A. Lange, Pastor, states "I hereby certify that Heinrich Mesinbring son of Heinrich Mesinbring and Dorothea his wife has been sent to scool to me by Mr. Heinrich Dedeke with few exceptions during the time from the first day of October 1857" etc. Doro Mesenbrink was the wife of Heinrich Dedeke. I will be glad to share further information.
