Napolean's Port Desha County, Arkansas is located approximate 55 miles east of where his son, Thomas Jefferson Green, was living in 1850 and 1860; Miller Township, Bradley Co., AR.
I found this lead through Ancestry.com. The caviat to this lead is that the middle initial for Thomas Howard Green could either be N or H.
I do not know if this is my ancestor but, am looking for clues to rule him in or out.
Thanks for any and all help!
