I am searching for Jacob Helferich

I am looking for information on Jacob Helferich of Port Austin Michigan. I understand some of the family may have been in Macomb County. I notice Debbie Morr has a Web Page set up on FamilyTreeMaker.com but her email [email protected] bounces and her phone number is no good either. She must be around as her web page was updated in Sept. If anyone knows her could they please contact me or if you have any information on the Helferich family I would like to hear from you but especially Debbie as she seems to have a lot of information on my family. She says she lives in Ia. but I can't find her there either. Please Help me find my relatives.
