What ever became of the Montgomery Journal? It disappeared and was subsumed, with the other Journals, into the Washington Examiner which recently published a short article on slavery in Montgomery County. The county had been trying to publicize the problem, asking people to be aware, to call 911 or 1.800.599.9291 if they have any suspicions.
For more information on slavery and its many forms we have this recent 2 volume reference work:
