Have you looked in Pennsylvania or New Jersey? Our Dunns(mine was also a John Dunn b. in Pa n 1752, in Ireland, son of James and Martha. They lived in Va and Pa for a while during the RW. and finally went to Ky.) . There was a large clan of Dunns across the river from Pa in New Jersey. I believe of Hugh Dunn. You may find your Thomas there. It is always possible Hugh and James were related, but we have not found a connection-wish we could as they all seemed to have the same names and some of them ended up in Ohio and possibly Ky, also.
