According to “Village of Ossining Significant Sites and Structures Guide, Page 85“:

The Calvary Baptist Church Annex, originally built as the rectory for St. Paul’s Episcopal Church, was constructed in 1864 to house the congregation’s minister. When the congregation moved to its current site in the Town of Ossining in 1958, the Annex was purchased by the publishers of the Citizen Register newspaper, who used the building for their offices. In 1973, the newspaper donated the Annex to the Baptist congregation that owns and operates the Calvary Baptist Church today.
