Hi, while I do not appear to have a link to this family I do have a brief piece of information about this family. This is an excerpt from the Economy/Hallsville, Ohio Sesquicentennial guide - June 21-22, 1987.

"In 1796, Conrad Bitzer came with his wife from Berks County in PA via Portsmouth to Chillicothe, Ohio, passing but one hut on the way up the Scioto. They settled for the winter in what was probably an abandoned indian cabin, on Blackwater Creek in Green Twp. His son John was born here in June, 1797. In 1801, they moved to the west half of Section 18 in Colerain Twp. That year a daughter, Elizabeth was born. She was probably the first white child born in what is now Colerain Twp."
