I am not sure what you meant by the information before James seems only to be guessing. I think there is pretty good documentation that he was a son of 1816 (year of death) Robert Wright of Nelson County, VA, (place of death).
The 1800 Personal Property Tax List for Amherst County, Virginia, listed James Wright (Son of Robt) with one tithe.
There are a number of documents and the 1810 Census placing James Wright in Catahoula Parish, Louisiana.
Then on January 10, 1818, at Nelson County, Virginia, D.B. 3/142 James Wright of Catahoula Parish, Louisiana, appointed his son Robert Wright to act for him in connection with his interest as an heir in the estate of his father Robert Wright of Nelson County:
"Before me Thomas C. Scott Parish Judge in and for the parish of Rapido and Exd Offices notary Public came James Wright of the Parish of Catahoula who declared that for divers good causes and considerations he hath nominated constituted and appointed and by these presents doth nominate constitute and appoint his son Robert Wright also of the parish of Catahaula his true and Lawful attorney for him in his name and behalf with power have demand sue for and recover any and every thing which may be due owing or coming to him whether in money or property as one of the Heirs of the Estate of his late father Robert Wright of Nelson County and State of Virginia into whose several hands it my befrund(?) and to make and execute proper receipts and acquittances for the same with power to do whatever may appear conducive to his interest in all affairs in which he may be concerned in the said State of Virginia to accept or reject successions to acknowledge debt, to compromise & refer to arbitrators, to make transactions in matters of litigation to sue for restitution in integrum with regard to an act, to alienate moveable & unmovable property to appoint a substitute or substitutes. And he the said James doth hereby ratify and confirm whatever his said attorney may Lawfully do or cause to be done in the premises as fully and intirely as tho he were personally present. In testamony whereof the said James Wright hath hereto subscribed his name at the Town of Alexandra in the Parish afored this twenty fifth day of August one thousand Eight hundred and eighteen.

This power of attorney is similar to others filed on behalf of the children of 1816 Robert Wright of Nelson County, VA, as part of the administration of his estate and clearly identifies James Wright as a son of 1816 Robert Wright.
