Hi Allison,
I found one James Roberts who 'Rendered Materiel aid' to the men of the Revolutionary War, from Connecticut. Since he helped in the War, he would be considered a Patriot. You haven't given me any other information so this may be a different James Roberts, but here is what I found: James Roberts was born 2 May 1739, in Windsor CT. He died 9 Dec 1796 in Windsor, CT. He was married to Jerusha Talcott, and I have found 3 children for him, (he may have had more) Sally, who married Daniel Talcott, Elihu, who married Deborah Munsell, and Jerusha, wo married Elijah Mather. You can read more about him in the Connecticut Revolutionary War Accounts, Ser.1 Volume 1, pages 385 to 387; Volume XVIII, pages 324 to 326. I hope this helps you! Good ancestor hunting!
