First Baptist
In 1819, a non-denominational meeting-house was erected in the city of McKeesport on a parcel of ground donated by Mr. John McKee. On June 3, 1820, the Baptist people of the community met and organized a church. The Rev. William Stone was chairman of this organization meeting. The recorded meeting was held on August 5, 1820, at which time it was decided to administer the ordinance of the Lord's Supper quarterly.
The church was admitted into the Pittsburgh Baptist Association April 10, 1841, with a membership of fifty. One year later, the membership had more than doubled. The first edifice was dedicated December 25, 1868. In 1887 the West Side Mission was established. The present church edifice was dedicated June 19, 1904.
The church was purchased by Zion Baptist Church in 2005. I can't find any other information.
