I would like to develop the tree for the descendants of the above couple. He was born 14-jun-1815 in Saarlouis and Rosalie on 3-Feb-1823 in Bad Kreuznach, married in Saarlouis on 26-Jul-1896. They had 8 children (I think). I would like to contact anyone who has information on their descendants -- , Adolf is my 3rd great Uncle.
