Robert J. Yeager, son of Joshua, was born in Allentown, May 7, 1833. He was educated in the Allentown Schools and at Nazareth Hall and became a clerk in the dry-goods store of Weinsheimer & Newhard. Subsequently he conducted a lumberyard in the first Ward for several years. He then devoted his time to the cultivation of his forty-five acre firm located between Fifth and Seventh Streets and North of Allen Street, until the encroachment of residences through the growth of the city made this impractical. Mr. Yeager died March 3, 1914, aged eighty years. He was a member of St. John's Lutheran Church. Mr. Yeager married June 6, 1854, Matilda Deily, daughter of Jacob and Mary M. (Geisinger) Deily of Catasauqua. They had three children: Albert J., Andrew L. and a daughter, who died young.
