C. Ashley Ellefson, professor emeritus of history, announced that in October his manuscript, "Seven Hangmen of Colonial Maryland," was added to the Archives of Maryland Online, the Web site of the Maryland State Archives in Annapolis, Md. Included with the manuscript are 71 charts that Ellefson began working on in the 1960s and that include the 477 executions, including one burning, possibly alive, pardons, reprieves, gibbetings and quarterings that he has found in Maryland, mostly from 1726 through 1775.
