You say "he was born in kentucky and moved to virginia, later the state split and now that part is west virginia."
So ~what~ part is now WV? What County did he live in, in WV, and when?
If he was held at Camp Chase, he probably was a CSA soldier.
First place to look is the National Park Service's database of soldiers:http://www.itd.nps.gov/cwss/
--click on "Soldiers" and use the search box, don't forget to try spelling variants and consider that some men used mainly their middle names.
If the Tennessee soldier is your target person, there are databases on the internet that have enlistment and service information, plus files concerning widows who applied for and/or received pensions. They are on for-pay sites such as Ancestry.com and footnote.com (which has a free trial), and on the InternetArchive site but not indexed there.
Again if the Tennessee soldier is your man, do research on his regiment(s) and especially members of his Company. The above site will list everyone known to have served in the same Regiment, you will have to do some work selecting folks from just one Company from the list. Single Companies were often recruited from one pretty small geographic area, usually within one County.
If you find out where at least some of the men of the Company lived before and after the War, you may learn something about your man's neighbors and possibly kin, and quite probably where he lived last.
You can find this out by looking at the US Census enumerations for 1860 and 1870. Images of these Census enumerations are indexed and available at Ancestry.com, footnote.com, Internet Archive, and some USGenWeb sites have transcripts available.
You might have some luck searching at https://familysearch.org
, they are adding new databases all the time.
For vital records in WV, check out the searchable birth, marriage and death databases at the WV State Archives:http://www.wvculture.org/vrr/va_select.aspx
--after you click on one of the links to search, do read through the information on how to use "wild cards" in your search. And, again, use your imagination for name spellings.
On Ancestry.com if you are not a paid subscriber you can see only the free indexes and start your own tree - not look at others' trees.
In future when you post queries, it will help readers help you if you give specific locations - particularly County names if you know.
You may get more help by posting on a Message Board for your man's surname and for any specific places (Counties) you know he lived in.
When you post these queries, it is great to give full names and dates in the subject line, as you did here, but also include what place name you know he lived in and when. People on these message boards are not going to know much about Camp Chase, but a residence location can help ring someone's bell if they know something about your target family.
Good hunting to you!
