Gregg, Michael Knauff is also my ancestor.My gggrandfather. I have quite a bit of genealogy, but there are some missing dates that I would like to fill in. I was born and raised in Portsmouth.My ggrandfather married Elizabeth Knauff and lived in Buena Vista in Scioto County.Several years ago I spent a lot of time searching the Knauffs.Even went to Zelienople, PA where Michael came from and got some great information. Would like to share information with you. Please get back to me.Thanks for posting on the WEB site.
