Jacob Yeager, prominently identified with the establishment of the Evangelical Church in Lehigh County, was born May12, 1809. He was brought up on a farm and learned the trade of blacksmith, which he followed until 1838, when he directed his attention to farming. He first leased, from Charles Mertz, a farm in South Whitehall township, (now the Poor House property) which he operated for three years; then he purchased from Mr. Mertz another farm of 76 acres at East Texas in Lower Macungie township, (now the property of Mi. Miller), which he carried on successfully for nearly thirty years, until his decease, June 30, 1869, and was buried on July 4. He and his wife were among the original members of the Evangelical Church in Lehigh County, and became intimately associated with Bishop Seibert in his introductory religious work in the community.

Mr. Yeager was matted to a Miss Williams, and they had two children: James, and Angeline. Upon his wife's decease, he married Susan Fensteimacher, daughter of Jacob Fenstennacher of Longswamp Township, and by her he had nine children. His second wife was bom May 20, 1812, and died Feb. 29, 1872. Interment was made in the Mertz cemetery near Wescoesville, by the side of her husband and children.
