I have about the same info. that you show on your post . Tell me a little more about how you tie in with the Dunklebergers. My line is Engel of Ufer > Adolff > Adolff > Wilhelm > Clemens > Clement > Anna Maria > Anna Fry > Pascal Jackson Blackburn > Eliza Jane Blackburn > Margaret Austin > Sue Smith( my mother ) . I have gotten most of my info. from the internet and from family members and have very little documentation . Do you have any firm sources of the line to Engel of Ufer ? Would like to share info. if you think it would be helpful to both of us . Send me your email address .
