In case you are still having any doubts about there being other members of the Red Rovers in Texas who were not from Alabama can also cite historical records of their movements from Alabama to Texas.
In Cpt. Jack Shackelford's company of Red Rovers from the Courtland, Alabama area there were fifty-five original volunteers who made the travel with him to Texas.
Boarding the cars of the Tuscumia, Decatur and Courtland Rail Road, the Red Rovers left Alabama on 12 Dec 1835, transferred at Tuscumbia to the steamer William Penn, traveling to Paducah, KY where they boarded the steamer Kentuckian, traveled down the Mississippi River and arrived at New Orleans about a month later.At the port of New Orleans they boarded the schooner Brutus and landed at Matagorda Bay on 19 Jan 1836.
So, by my lowest count there are four volunteers from St. Louis, Missouri on the steamer Junius traveling down the Mississippi River and reaching New Orleans 6 Jan 1836, according to Dr. Joseph H. Barnard, and all who went on to join the Red Rovers probably after reaching Texas as Dr. Barnard did.
Dr. Barnard goes on to state that he embarked on the schooner Aurora, same ship that John N. Barnhill and Zachariah (Shore) Short were on, 10 Jan 1836 and made a passage of five or six days to Matagorda Bay.
Have already mentioned Dr. Joseph Barnard joining the Red Rovers 4 Feb 1836 after several weeks of confusion among the volunteers because there was no army or regular troops in the area to direct them.
My thinking is that some of these volunteers for Texas were not connected to any company of men, lived in surrounding states and just traveled to New Orleans.What they did after reaching either New Orleans or Texas was to join whatever company appealed to them.Possibly either because they had family in Georgia, Alabama or whatever company they came in contact with at that point in time.
Would like your thoughts on this subject Stan and wish I could get you interested again in researching the early history of Texas.Sounds like you are deeply into the Barnhills and related families of Virginia right now and can understand how all consuming it can be when on the hunt...smiling.
