In reply to KRG.

Rev. Georg Burger served two congregations in NW Ohio - Zion, Schumm, in Van Wert County and St. Paul's in Liberty Township of neighboring Mercer County. After Burger's death just a month before the April 1847 meeting in Chicago, Rev. J.G. Streckfuss represented the two congregations as they joined the synod. St. Paul's later left the LCMS and is now a member of the ELCA.

According to the Concordia Historical Institute's website, the Lutheran congregation(s) at Peru, Illinois is/are no longer in existence.
