Rev. Michael and the Reformed Presbyterians

The Reformed Presbyterian Synod met in Pittsburgh on May 25, 1868 with Rev. Michael Harshaw in attendance and speaking.  The Pittsburgh paper reports their deliberations, which seem stormy.  Though the exact issue isn't clear it's possible that it was united with the larger Presbyterian church. (Much discussion about reunion after the Civil War.) 

 Rev. Michael leaves the Reformed and joins the United in 1870.
