JACOB DeLONG.

Jacob DeLong, a farmer and stock-raiser of Bear Creek township, was born in Fairfield county, Ohio. November 14, 1847, being a son of Abraham and Elizabeth (Mowery) DeLong, natives of Fairfield county and Hocking county, Ohio, respectively. The paternal grandfather, Abraham DeLong and his wife were born in Germany (sic) and on coming to the United States settled in Ohio. He was a farmer, an occupation which he pursued all his life. He died in Allen county, Ohio, his wife surviving him and also dying in Allen county, Ohio, at the advanced age ninety-six years (sic).

Abraham DeLong removed from Fairfield, Ohio, to Allen county, Ohio where he followed agricultural pursuits until his death, in 1863; his wife died in 1851. They were the parents of three sons: William resides in Hocking county Ohio; Jacob, whose name heads this sketch; and Isaac of VanWert county, Ohio.

Jacob DeLong was reared and educated in Fairfield and Allen counties, Ohio. In 1863, when sixteen years of age he enlisted from Perry county, Ohio, and was mustered into service as a private in Company D, Seventeenth Ohio Volunteer Infantry, the term of enlistment being for three years or during the war. He served in the Army of the Cumberland and took part in the battles of Missionary Ridge, Ringgold, Buzzard's Roost, Resaca, Kenesaw Mountain, Atlanta, Nashville, the Carolina campaign, and participated in the grand review in Washington, D. C., in 1865. He was honorably discharged at Columbus, Ohio, August 8, 1865. After being mustered out of service he returned to Perry county, Ohio, and on October 1, 1868, was united in the bonds of wedlock to Miss Miriam Poling. She was born in Hocking county, Ohio, her parents being John and Margaret (Graffis) Poling, natives of Fairfield county, Ohio, and Pennsylvania, respectively. John Poling was a farmer and died in Hocking county, Ohio, June 21, 1875. Mrs. Poling died January 7, 1869.

Jacob DeLong, the subject of this biography, resided in Allen county, Ohio, until 1879, at which time he moved to Bear Creek township, Jay county, Indiana. Here he purchased one hundred and seventeen acres of land on which was a log cabin, but very few other improvements. He now has his farm under a good state of cultivation, adorned with a comfortable dwelling and barns. As a stock raiser he has many valuable animals, among which might be mentioned: Full blooded, registered short-horns, and two full blooded Scotch bulls, one, "Royal Monarch," four years old, and the other, "Rosa Bell Archer," three years old, each weighing two thousand pounds and very handsome and valuable animals; he also has a blooded heifer and calf, which were a part of the fine stock sale in Indianapolis in 1901. Mr. DeLong raises full-blood cattle for the market, selling at the ages of one and two years old; he now has twenty-eight full-bloods. He began the raising of fine stock in 1900, at which date he purchased an imported bull, the first brought to Bear Creek township, and has increased the business until he and his partner, Mr. S. H. Straley, are considered the leaders in Jay county in their line. Mr. DeLong is a pioneer in Jay county in the raising of blooded stock.

Mr. DeLong built his residence in 1889, after living ten years in a cabin which was on the farm when he purchased it. He has cleared the land, tiled it and is now one of the most prosperous and well known farmers of the county.

Twelve children have been born to Mr. and Mrs. DeLong: Margaret E., born February 16, 1869, now Mrs. Hewey (sp), of Wabash township; Frances E., born June 2, 1870, died December 16, 1893; Clara C., born February 16, 1872, died March 8, 1893; Isaac A., born November 3, 1873, died May 19, 1877; Effie M., born May 2, 1875, died March 22, 1901; John M., born June 2, 1876, died November 8, 1876; Levi E., born September 2, 1877, enlisted in the Spanish-American war in 1898 and served as a private in the One Hundred and Fifty-seventh Indiana Volunteer Infantry, at Tampa, Florida, until discharged. He is now in the employ of the Panhandle Railroad at Logansport, Indiana; Bertha J., born August 28, 1879, died October 30, 1886; Alpheus A., born October 30, 1881; Samuel E., born December 31, 1883; Chauncey M., born December 17, 1887, died January 22, 1900; Carrol H., born March 20, 1890. In politics Mr. DeLong affiliates with the Democratic party, while religiously he and his wife are members of the M.E. Ch. of Pleasant Ridge.

INCONSISTANCIES NOTED:
It says the grandfather Abraham (14-2) was born in Germany, while Abraham himself in 1850 reported PA birth.
It says the unnamed grandmother was also born Germany, but three censuses state VA. In 1880, son Isaac confirmed a PA father and VA mother (sons Daniel and Abraham Jr., both also alive in 1880, have not been checked for their statements).
The article also says the grandmother died at 96; she was 87.
