I recently started researching my family history and have came across your message while searching through www.google.com It mentions about a John marring into the arnold family of zuzenhausen, Germany I have traced my ancestors to there in 1681. I dont know if i can be of help but i do have a few names of the arnolds. Wendel Arnold was born in 1681 and married Anna Cathrine Shneider. There son Johann Gorg Arnold also of zuzenhausen married Anna Marie Barth. Maybe these could be the parents of the female your john married. Sorry i dont have any info on any other siblings at this time but will help if i find more info.
