This might be the connection I've been looking for. I have a document answering a letter written in 1971 by an Aunt, from the Headquarters Missouri National Guard. She requested information on James Morgan, Lafayette Banta and Milton Banta. She must have had some information on them in relation to James. The document has the wrong James Morgan, who actually deserted "at Arcadia Illinois" - his age was 28, making him born @ 1834 and was not "our" James, as we have most of his story. Milton Banta enlisted in 1862 at 22 years of age, and Lafayette enlisted in 1864 at 18 years of age. There is one memo that James tried to enlist but was too young, but large for his age, and was used as a messenger. The Gov't document correctly identifies the "Banta" name. I have little faith in whomever entered information on the Census, as many Census documents are filled with incorrect names or erroneous information. I'm leery of the 1850 Census with name of Martin Morgan, but is food for thought and further research. It's possible he married and fathered a James Morgan.
Thanks for your providing this information. It doesn't resolve the names of James' parents, but certainly fits with my family records that the Banta's took him in at a fairly early age. Gives me more fodder to search deeper. Muchas Gracias from El Paso..!
