Nope - no interest in the name; call it a random act of kindness. I know your frustration - I have several people that I can't find parents names for.
One of the things I would suggest that you check into, is the D.A.R. records. I believe there is a database on Ancestry although I could not find it easily. These records typically give ancestor names going back pretty far and how they are related. Although sometimes it's an "allied family name" looking for membership to DAR - that makes it a little tougher to find.
(Just curious - I saw a "Whittington Clifton" - is he related to your George? If so, perhaps HIS or other sibling's trail of paperwork could lead to parentage.)
I am interested too in the history of the Revolutionary War, especially as it pertains to Delaware. :-)
Happy hunting!

Here's an interesting link - although this doesn't help much with parentage ...
