While still a Sunday School, the members had purchased a Presbyterian church building in 1842. This was the congregation’s home until 1870 when they sold the building and purchased other property upon which they built a new church, dedicated on May 26, 1872. An organ was purchased from Henry Knauff of Philadelphia and dedicated on May 24, 1872.

The Knauff organ served the congregation well. In the minutes of the congregational council there are several references to the instrument: the October 1871 minutes note that “Mr. Knauff thought that an organ such as we wanted could be built for $2,500 to $2,700; in September 1876 the congregation paid F.N. Robertshaw $25 to tune and repair the organ; in April 1879 the congregation engaged “Mr. Barkhof [sic] to attend to the organ, keep it in repair and tune for the sum of $25 p/annum [sic]”; in 1883, the congregation paid Knauff $73 to repair the organ. (Mr. Knauff’s hotel bill was $11.) The last person mentioned (1885) to tune and repair the instrument was Alex Ross.

Opening concert 24 May 1872 by the builders. Rebult by Moller in 1910 (in a new building?), which in turn was later replaced by a Wicks. One pedal rank in this instrument may be from the Knauff.
