We do not know if he ever filed application for a pension.
To begin with, where was he living during the later years of the 1900 century? It would be that state
where he may, or may not have filed.
For starters, try a Goggle search, such as, Confederate Virginia Pension Applications, Confederate Arkansas . . . ., etc.
If that search comes up with an index, you can begin that search there.
If you do find one, those having access to Ancestry.com may be able to locate and read. Also, the application papers
can be procured through this message board.
