These Judt's are the Catholic Jundt line.
Hans Heinrich Jundt born 1790 line is all Lutheran.
Hans Heinrich Jundt 1790 could not and was not the son to Mathias and Elisabetha Pflodt. The Jundt's you listed all belong to Peter goldbergs line He has traced his Jundt line from Germensheim, Pfalz all the way back to 1580.
It would not surprise either of us if his ancestors (before 1580) had also originated from the Basel area -- We just have not been able to find any documentation/records to support such a theory.
