I'd give up on that one. He doesn't fall under the time period for DAR eligibility. See:

That said, when you have one ancestor living in the Colonies at the time of the Revolution you are sure to have more than one and I'm sure you will uncover other avenues that will be more in line with the DAR requirements for membership.

Best of luck in your search!
