Flint can definitely occur in sedimentary deposits, so that would not surprise me to occur in Ohio. However, the first picture you posted is clearly a smoky quartz, and that's highly unlikely from Ohio. Smoky quartz is most likely found at pegmatites, and although possible that you found such a deposit, its unlikely.

The other quartz specimens you posted could indeed occur in ohio, though the ones with tourmaline included inside would again indicate a pegmatite occurrence, which is not possible in sedimetary limestones or shales which is mostly the composition of Ohio.

Hershel, I do not claim to have a bunch of knowledge about geology and or mineralogy and I appreciate your feedback, however while it may be unlikely that the smokey comes from Ohio, I can assure you that some of my specimens have been chiseled and lifted off of hard rock, and if that hard rock was brought here it would have been tough to do so given the size of the rock formation it came off of. Did I mention that this is all coming from a hole about six feet deep covered in old indian waste mining. The other guys that dig here swear the rock was probably a big boulder heaved aside and left while natives mined the flint deposit here in central ohio... I have also been told by a geologist friend that there is a cherty sort of limestone that exists and could have formed with the Ohio Flint deposits as well??? Which may allot for your pegmatite conclusion??? Also I just nabbed another 50 pounds of specimens yesterday, some smokey, some clear, some druzy some clusters, so there is more still... and a side note.. I was told that the inclusions were not tourmaline in fact but geothite possibly... thoughts? Again thank you so much for helping me solve this mystery!!

I never ruled out the possibility of the smoky quartz's coming out of Ohio - I just said it is unlikely. There is a small deposit that produced quartz and some of it smoky from Monroeville, Huron Co.

And yes, goethite is definitely a possibility. If you can somehow get some better close-ups that are clear maybe that can be determined...

It's all good... It's just exciting for me, to find something that may be rare, I'm just happy I've got some help in identifying what I have here... I'll get on taking some better clear photos and hopefully have em up tonight!
