I am researching the Deppe name. I have an Aplonia Deppe, who married Philip Berend and resided in the Franklin/Gasconade counties. I have not been able to find much info on her; except she was born around 1817. She is on the 1860, 1870, and 1880 Franklin county censuses, but all her children's records are found in Gasconade.

I don't know if I've helped or confused you more. Love to hear from you.
