Hi I just want to offer my help. I am a Weingaertner as well. If you recognize the coat of arms on this webpage (www.seehotel-weingaertner.de) I can offer you some help to find out more about the German part of your family. My family originates from Enkirch/Mosel as a starting point for you. If you have any questions please feel free to contact me. In a couple of weeks I will put some information on my webpage.
