When I put up the original Query I knew very lttle about the "Mill" My Great grandfather Thomas Webb b 1810 Harford County Maryland, was a part owner of the Hartfords Grist Mill along with John Newell. Found a lot about it in Craig Heaton's book Grist Mills of Tomlinson Run. I was at the mill site and made several photos of the mill site in about 2003
I also found the farm my dad grew up on it is out Gas Valley Road East of the High School on the right hand side of the road at the last right curve of the road befor it crosses in to PA. House is still there and I made photos of it also.
Still very much intrested in Webb's Baxter's Spivey's and Kinney's. both in new info and sharing what I have......
