This is what I have in my book, The Encyclopedia of Quantrill's Guerrillas, about Dan (Don) Vaughn: Served under Quantrill...Vaughn fought in the August 11, 1862, battle of Independence. he fought in the Lawrence Massacre. In August 1864, he was with Thrailkill in the Ray County fight. When Todd was buried, he stood over the grave and took a vow to avenge his (Todd) death. He raided Aubry, Kansas, January 31, 1865, where they burned many houses and killed a man from Fort Scott, Kansas. After the war, he went to Texas.

I believe that James A. was his younger brother.

After Quantrill's death in Kentucky, most of the men who rode with him(about 65 men), surrendered in Smiley (Samuel's Depot/Wakefield), Kentucky. This included Frank James. At Pocahontas, Arkansas, Quantrill and his men split. Quantrill, Frank James and several others went to Kentucky. Jesse James, George Shepherd and several others went to Texas.

I hope this helps you.
