Chaplain for 20th USCT, Rev. Geo. W. LeVere, was later the first pastor of the Shiloh Presbyterian Church of Knoxville, TN. , taught school under the Freedmen Assembly, headed up another school, helped start the Colored Mechanics of Knoxville, and served as national leader of many Prince Hall Masonic lodges that trace back to a Boston African American patriot with that name.
A web page devoted to American Revolution Col. Thomas Crafts Jr. includes the tri-corner hat image of Prince Hall, two paragraphs about him and a link to a PBS web page with a fuller bio mentioning his role helping found African American Masonic Lodges. See http://www.geocities.com/jcrafts525/
