Trying to find more information on this church in Washington DC. Familysearch.org shows a marriage between William H. Day and Caroline Zigler on 26 July 1871 by William A. Frey, minister of this church. Trying to determine where the church records might be. The record indicates the marriage took place at No. 614 "N" Street, NW, which may or may not be the address of the church. Thanks!
