This church was incorporated in 1844 by a group of men from the First Presbyterian Church then located at the northwest corner of East Fayette Street and North Street (now Guilford Avenue) in downtown (later relocated in 1854 to West Madison Street and Park Avenue in Mount Vernon-Belvedere neighborhood after selling their previous third church building of 1790-95 to the Federal Government which built a U.S. Courthouse there [to 1889, replaced again 1932] dedicated in 1860 by President James Buchanan).  They felt the need for a new church in that fast-growing northern section of the city formerly "Howard's Woods" of Col. John Eager Howard's (Revolutionary War commander of the famed "Maryland Line" regiment of the Continental Army) country estate "Belvedere" (mansion located at intersection of North Calvert and East Chase Streets, razed 1875) where the Washington Monument was erected with its four surrounding park squares just two blocks from their new building.  Franklin Street Church was also located on "Cathedral Hill" in the southern part of the community bordering downtown and across the street from the old Baltimore Cathedral (Basilica of the National Shrine of the Assumption of the Blessed Virgin Mary) erected 1806-1821 and designed by Benjamin Latrobe.

In 1973, the two historic congregations reunited to form The First and Franklin Street Presbyterian Church and was centered at the First Church site on West Madison and Park.  The Franklin Street building was used by the merged congregation for a time and then sold to a fundamentalist independent Protestant congregation and later re-sold to the present "New Unity Church Ministries".  Across Cathedral Street to the northeast was the 1820s era Greek Revival home designed by Robert Mills (who also did the Washington Monument two blocks away) which later was occupied by the original Maryland Club, an exclusive Southern-leaning dining and leisure society of gentlemen, founded 1857 that was once threatened by Massachusetts Militia Gen. Benjamin F. Butler, U.S.A. when he occupied Baltimore at the beginning of the Civil War on May 13, 1861, and fortified Federal Hill with a Fort and cannons overlooking the harbor and city, "to put a shot into it" if he spied a reputed rebel flag flying or any discontent to declared martial law.  The Club later moved to North Charles and East Eager Streets in 1892 and mansion was later replaced by the former Central Building of the Young Men's Christian Association of Central Maryland (YMCA) which was closed in the 1980s and the building renovated as the Mount Vernon Hotel and Cafe.
