Thomas Warren Jr. Orange Co., VA

Will be going to Orange Co., Va this summer to try and locate Thomas Warren jr. death location and anything else I find. He died 1785 and wife Avarilla Goodloe Warren died 1783. Thomas's parents were Thomas Sr. and Mary Hackley of Spotsylvania Co., Va. Wondering if anyone has been there for this Warren line. Any info would be appreciated and I'll share what I find. Thanks Tammy
