Larry, I'm a bit late on this one, but I have a Corneliua Clinton Ashworth b circa 1805 who married Hannah Mooney in Grayson Co VA, lived in Mercer Co WV and then moved to Illinois by 1860.
Now, of course there is Cook Co IL..not sure if that is what was discussed here ( some of the replies to your question)..and I don't know any more about Cornelius and family after they moved to IL. Here is what I have from the census images I saw online at ancestry.com.
Hope this helps..Debbie in VA
Oh by the way I have his ancestry..he is son of Samuel Ashworth and Elizabeth Brizendine..more if you need it!
