Hi, I have heard of this route. The New Orleans Greys- were a few thousand sent by Jackson (Covert Action?) and it was common to build log rafts up river and sell them to a sawmill near New Orleans, giving cash to enter Texas with. They could also go back upstream on a steamer to Natchitoches, La. and cross toNacodoches, Texas Martha Catherine Mitchell Wyly joined her Texas children and stepchildren by the Gulf of Mexico from Georgia, to Alvin Texas above old Indianola, on High Bank of old Brazos, which sunk during the Galveston Huricane of 1900, which set the record for Huricane deaths which still stands and gave the world the Mayor- City Manager type government before they could be reached by mainland. They were piling bodies from shallow graves and burning them in wrecked buildings for sanitary survival. The seawall was added with Burnett Texas Granite later. Take care, Charles Wyly
