I found the following information online:

Revolutionary War participants recognized by the Sons of the American Revolution (SAR). Taken from SAR Patriots Index.

Charles McClung, Private, Pennsylvania, born 1757/1758, died 1783, wife Margaret Young, son Charles McClung who married Jane Robinson.

I am hoping to verify it.

There is one person who used Charles McClung as his patriot in the 2006 membership directory. I can send the information via email.
