I have done extensive research on the Daul's in neighboring Ebersteinburg, but I know that Maria Eva Daul was born in Oberndorf, Baden 12/24/1810. There is probably a connection between the Daul's from both cities (Christian Wunsch's son Theodore from Oberndorf later married Caroline Daul from Ebersteinburg), but I have not had the time to order the Oberndorf films from my Family History Center to find out if there are more connections between the families. I would be interested in anything you find out about them. I do have extensive information on Daul's in Baden-Baden and Ebersteinburg if you would like to email me: lenoirj@charter.net.
