This is of late response but hope it will be of some use. The DeRosset(t) Surname is found in the Cape Fear area of North Carolina (Wilmington - New Hanover Co). The surname appears in Vols I & II of the New Hanover Co, NC Court Minutes (1739-1769) & (1771-1785). - I have not studyed the surname and am not familiar with the James D* Bryan(t). I do know that the neighboring county during that era had surname of Bryan(t) -often interchanged in later docs.
