Dorothy E. McElroy and Charles A. Earp, The History and Roster of the First Christian Church (Disciples of Christ) of Baltimore, Maryland - 1810-1996, Heritage Books, 1996. McElroy and Earp combed the archives of Govans and First Christian churches -- including rosters, directories, ministers' books of baptism, marriages, funerals, Sunday bulletins, monthly newsletters and other congregational records -- to compile a roster of about 5,500 members of the congregation from 1810 to 1996.
