My Deppert Family came from Gochsheim in Bavaria about 1850. John Michael came with his wife, Henrietta, and three children.They finally settled in Carlstadt, New Jersey in the USA. I have several hundred Depperts which I will be glad to give you if you are interested.
Unfortunatelly I do not read or write German.
Have you searched the Deppert name in the records of the Mormon Church?They have many names, both Catholic and Protestent.
Let me hear from you.Where do you live?I live in Wilmington, Delaware in the USA.Harry E. Deppert
