Biography
Margaret was a religious sister; took part in the 1988 Nuclear Navy Plowshares aboard the USS Iowa at Norfolk Naval Station, VA.
Separate Nuclear Navy Plowshares custody episodes
The original August 1, 1988 Revolutionary Worker, printed page 4, names Margaret McKenna among the four held since the April 3 action and reports her July 13 sentencing and actual release to supervised probation. The initially announced July 14 group hearing is not substituted for her actual day. The movement's historical chronology reports a later March 1989 probation-related sentence, reduced by credit for earlier confinement to an order for twenty additional days. Those are ordered days, not verified actual service. The chronology's reference to July 1989 for the original sentencing conflicts with the contemporary 1988 report and is not used. Exact custody endpoints for the later episode remain unknown; no continuous interval spanning probation is inferred. The existing identified photograph is retained.

The contemporary report individually names this participant among eight people arrested at the January 17, 2011 Martin Luther King Day protest at Lockheed Martin in King of Prussia, Pennsylvania. It reports transport to the Upper Merion police station and release on disorderly-conduct citations. It does not establish a physical jail-admission date, an individual release day or a measured custody duration. The protest included recordings of King speeches, a memorial litany and a tolling bell.

Art Laffin’s account individually names this participant among eleven people arrested on the Pentagon sidewalk during the 2012 Good Friday witness after three warnings to leave. It reports a failure-to-comply-with-a-lawful-order charge and a then-future May 18 court date. The Holy Thursday Israeli Embassy witness and the later White House witness are described separately. Contemporary source.
The Good Friday report names Margaret McKenna among seven people arrested at the Pentagon on April 3, 2015 and processed and released several hours later. The reported charge was failure to comply with a lawful order, with a June 4 court appearance still prospective. The symbolic crucifixion script and its named historical victims are separate from the seven-person arrest roster.
