My mother has done so much research about our Mortz history. She has sooo much information if anyone has facebook she is on there http://www.facebook.com/?ref=home#!/profile.php?id=100000691.... I know she went back into 1800's not sure about when but when John Moritz moved here from Germany in the late 1800's it was Moritz then in the early 1900's the name changed to Mortz. Putting this family tree togather has been such a puzzle to us. My mom is Valerie "Mortz" Rogers and we are from Kokomo, Indiana. My mothers father is Don Mortz. His siblings are Viola, Susan, james, and Duke.
