Where to get hazelnuts for seed

Hey all, does anyone have any suggestions for good sources to get hazelnuts for seed in the eastern u.s., especially near northeast Ohio? I'm looking for a couple hundred seeds preferably from a context of trees growing in semi-wild landscapes and ideally some selection for nut production, taste, and nutrient content.
basically just any source that other people have found to be of good quality and with significant genetic diversity throughout the different seeds. I was interested in trying to get seeds from Mark Shepard but all I've found online is that he sells plant starts rather than seeds.

thanks

Well... I live in Trumbull County & I have some hazelnuts growing along a roadside nearby, but nowhere near that many. I assume they're the native variety.

What did you want them for? Sounds like a breeding or research experiment, with the sheer amount.

The quantity is not really necessary I guess. I know of a couple american hazelnut trees near where I live that I'll harvest some from next month but I am planning to plant a lot around in abandoned vacant spaces and I was hoping to include genetics from various locations and start as many seeds as I can so that there will be adequate production for wildlife in addition to plenty to harvest for human use. also planning to do this with hackberry, sweet crabapple, chokecherry, black elderberry, and smooth roses. probably others too.. really tired of not having a chance to start creating functional habitat due to living in a city and being poor, so it's time to disregard absentee claims of possession called "land ownership"

If you're still looking, you can order American Hazelnut from Prairie Moon Nursery, but I don't know if it's seeds or whole trees only.

I heard about some newish hazelnut variety that is immune to the plague or blight that many hazelnuts suffer from. im not sure where they were created, I want to say university of Maryland--maybe, I don't remember but might be worth looking into as healthy nut trees grow and produce for decades
I got a bundle of 25 from the state of Tennessee dept of forestry a couple years ago, not these new ones and planted them out in the wilds of my property

here is a link to what im trying to say

rutgers (new jersey) is where a lot of the new blight resistant selections are coming from. the effort is currently being led by tom molnar.

tom Molnar that rings a bell. I heard about this on NPR  a while back. it made me want to get some of these new varieties but  have yet to really look into it, my hands are kind of full with all the chestnuts and other stuff already growing.
Alex I understand where your coming from with lots of trees, im into almost 500 chestnut trees, and about half will probably have some nuts next year. its a long term proposition but once they are growing well your grandchildren will be harvesting bumper crops hopefully. many nut trees take something like 5-8 years before they produce.
if you are open to using barefoot seedlings, I know one state that will ship out of state is West Virginia if they have any of what you're after. the Tennessee dept of forestry seedling program usually sell out real quick of highly desirable things like nut trees I got my order in on the day the sale opened but the next year went back for some more and was a day late they had sold out. one year bareroot seedlings are very simple and quick to plant using a hoedad or a dibble bar in winter or very very early spring.

got me into a hazelnut research mode
