I cannot find that John Russell Young ever again wrote articles in The Press as "The Wanderer." One reason may have been as follows: The Wanderer was also the name of the last slave ship known to have ever landed its illegal cargo in America, and by 1860 using the name Wanderer would have been professional suicide for an aspiring young Northern Democrat from Philadelphia.
