Who died last? The fate of the Lincoln Conspirators

What was the fate of these men? My biggest question is who died first? Who died last? Here is the accurate list.

1. John Wilkes Booth-->Booth went first, he died on April 26, 1865
2. George Atzerot, Mary Surratt, David Harold, Lewis Powell all went on July 7, 1865
3. Michael O'Laughle died on September 23, 1867 while serving his prison sentence.
4. Edmund Spangler died on February 7, 1865
5. Sam Mudd (Not proven to be directly involved in the Booth cnspiracy) died on Janurary 10, 1883
6. Sam Arnold died on September 21, 1906. He was one of only two conspirators to survive into the 20th Century.
7. John Surratt lived longer than any of the other conspirators. He died on April 21 1916.
