Updated through online information from Steve Bartley. -- The organ seen in the photograph is by Henry Berger. Based on the following article in the Baltimore Sun Paper. 3/24/1854
Handsome Church Organ- Mr. Henry F. Berger, organ builder of this city, has just completed a beautiful and fine toned organ for the Protestant Episcopal church at Monkton, Baltimore County, Rev. M.L. Forbes, rector. The case is gothic style of architecture, 9 ft. in height, 5 ft. wide, and 3 ft. deep, and contains a variety of pleasing stops, sufficiently powerful for a choir of twenty effective voices.
On the front is a silver plate containing the following inscription, "This organ was presented to St. James' Parish by John Slade of Harford County," which is expressive of the christian liberality of that gentleman. It has been erected in the church, and performed on by the builder, in the presence of the congregation.
The organ was replaced in 1949 by Aeolian-Skinner Op. 1148.
