JOSEPH G. JACOBS, druggist and pharmacist, Springfield. Just fifty years ago, Isaac and Letitia Jacobs, with a little son of two years, emigrated from Lancaster Co., Penn., to this county, settling in Harmony Township, their entire worldly store being one wagon and three horses. In those comparatively primitive days, turnpikes were unknown in these parts, railroads had not even troubled the inventor's brain, and the village of Springfield boasted a population of one thousand souls. Times were hard, trials and hardships many and fortune rolled on leaden wheels. But the sturdy and unflagging spirit of industry and continued perseverance won, and Mr. and Mrs. Jacobs were rewarded by ample and satisfactory success. They raised six sons and one daughter. Two of the former served in the Union army through the war, and one for a period of four months. Their youngest son, Joseph G. Jacobs, was born in Harmony Townshp on Nov. 3, 1850, entered Prof. Chandler Robbins’ Preparatory School in 1863, which he left in 1868, and spent five years teaching school in Clark and Greene Counties. In 1873, he engaged in the drug business in Springfield, and is now junior member of the firm of Troupe & Jacobs, doing a prosperous business on the southeast corner of Main and Market streets. His father died at the age of 65, and his venerable mother is at 70, still living in Springfield and in good health. In 1876, Mr. Jacobs led to the altar Miss Una Stuart, of Clifton, Greene Co., the beautiful and accomplished daughter of Elder R. and Rachael E. Stuart— of one of the oldest families in this country and of remarkable longevity, her grandmother Stuart dying Sept. 23 of this year (1880) at the ripe age of 82, having raised a family of eight sons and one daughter, all living and well-to-do and in their teens, the parents of large families, all save one of whom are living in this and Greene Counties. Mr. and Mrs. Jacobs have a boy of Ó months (Fred P.) and. a daughter of 2 years (Grace Iva), both children of unusual sprightliness and beauty. Mr. Jacobs is a member of Lagonda Council, No. 151, Royal Arcanum, and with his wife members in excellent standing of the Second Presbyterian Church. He is a young man of pleasing address, many friends, full of energy, enjoys the excellent opinion of those who know him, and his future promises well.
