Rev. John Adam Leiss served as minister of David’s Church, Killinger, Dauphin County, from about 1844 to 1856.
____________________________
Rev. John Adam Leiss was born in Berks County, Pennsylvania. In his early years he worked as a carpenter. While helping to erect First Reformed Church, Lebanon, He met with a serious accident, which made a deep impression on his mind that he felt a call to devote himself to the work of preaching the Gospel. He began his public ministry in Ohio. He then returned to Pennsylvania and became pastor of the Belleman and Friedensburg churches, which he served until 1838.
He later moved to Wernersville. While here he preached in a schoolhouse at Fritztown, Berks County, on a Sunday morning. The effort was too much for his enfeebled health, and proved to be his last sermon. After the close of the serviced, we went to the house of a Mr. Zion for dinner, expecting to preach in the afternoon. He was in the house only fifteen minutes, when he sank to the floor and in a few minutes was dead. He is buried in the Hain’s Church cemetery.
