I can't help you directly with George in LA, but I've been interested in the George in Abbeville SC in 1790 for quite some time.It was thought that he might have been father or maybe even older brother to my husband's 3rd great-grandfather Samuel L Cathey (b 1776 in Union Co, SC, died 1850 in Cannon Co TN, wife Margaret, children Jane, Samuel B, an unknown son, JAMES FERREN CATHEY, and William.)
We had thought that our Samuel, also in Abbeville Dist in 1790, was possibly a son of this Abbeville George, until we found a document wherein Samuel himself testified as to his place of birth, his father's name and year of death, etc.
The following quoted text is PART of the text of an application made by one Joshua Dover for a Rev War pension.Samuel Cathey was one of those being questioned as to the background of Mr Dover.Within the Dover document, Samuel goes into his background somewhat.The details fit perfectly with what we already knew, and he mentions his father's name, death date, and the fact that his father fought in the Rev War.Samuel states that he was born in the Union District of South Carolina, and grew up in Burke Co, North Carolina.
I don't know if this will provide anything at all to you, Stewart, but it was a gem of a find for us descendants of Samuel L Cathey.
"Samuel Cathey a citizen of Bledsoe County with whom I am well acquainted, and who is a man of ---ibility [?] and respectability, also came before me and after being duly sworn according to law deposeth and saith that he was born in the year 1776 according to the best information which he has received, that he was old enough before the close of the revolutionary war to notice & recollect some incidents which occurred [?] in it - he has been well acquainted with Joshua Dover for about forty years (the same person who makes application for a pension under the Act of 7th June 1832). Affiant about the time of his first acquaintance with Dover often heard him speak of his services in the revolutionary war. He often boasted of his service.Affiant often heard him recount the circumstances of his services in conversations with others who were then said to have been in the war - with Samuel Stout - a Wm [B?]urchfield, and with affiant's father, Archibald Cathey, who died in 1810, and whose return from the army on one or two occasions, affiant remembers, and which he believes are the earliest circumstances upon which his memory can falter [?]."
"This was in Burke County, North Carolina where affiant, having been born in the Union District South Carolina, was raised. It was generally said, understood & believed there that Joshua Dover had been a soldier in the service of the United States in the revolutionary war. Affiant has known Dover most of the time from that to the present - has been intimate with him for many of the last years and knows that he cannot from loss of memory and mental inability detail the circumstances of his service as he formerly could."
"Subscribed & sworn to before me the date above Samuel Cathey
