Hello Dyan,
the Karl August Degen is a relative of you. I got informations about the Degen family of Bardenfleth / Elsfleth. Karl August is a nephew of your Karl Heinrich. The Degen family made genealogical researches. So I think Karl August can help you.
Because I´m working on the page www.auswanderer-oldenburg.de I wrote your informations on this page. If you don`t like the publishing I can make it impossible to see these informations.
Regards,
Gunter (Jüchter)
