Jonathan Plowman conveyed to pastor John Davis, John Whitaker and Samuel Lane, Particular Baptists, a parcel of land, containing , for the sole use of a meeting house for the worship of God, forever. This fact was recounted in an act the state of Maryland passed on January 22, 1829 to incorporate Particular Baptist Gunpowder Church in Baltimore County. In the 1850s Jonathan Plowman's grandson Joshua Plowman member of Black Rock Particular Baptist Church was appointed as one of the trustees to oversee the sale of the land which Jonathan Plowman Jr. had donated to build the Particular Baptist Gunpowder Church. The church meeting house had fallen down and the congregation broken up and all the appointed trustees were dead.
