Dear Joan,
My ex-husband has Ade ancestors from Wuttemberg. Jakob Ade married Victoria Mosbacher in Oberndorf in 1755. Their grandson, Ingnaz Ade, moved to Ravensburg, also in Wurttemberg.
I havent been able to identify my ex-husband's earlier family members, but know there were quite a few Ades in Wurrtemberg. Some were there in the early 1700's, and others were immingrating in the mid to late 1800's. They seem to have lived in a variety of places within The Kingdom of Wutremberg.
Always,
Lynn
