From History of Pickaway County, Ohio and Representative Citizens (1906)
DSAAC LUDWIG, a venerable and highly esteemed resident of Pickaway township, where he engaged in agricultural pursuits through many years of active life, owns a finely cultivated farm of 13 1 acres not far distant from Circleville. Mr. Ludwig was born September 21, 1834, and is a son of Jacob and Esaline (Morris) Ludwig. The Ludwigs, a family of German extraction, came to Ohio from Pennsylvania and Daniel Ludwig, the grandfather of Isaac, was an early settler in Circleville township, his old farm being now the property of our subject’s brother, David S. Ludwig.
Jacob Ludwig was born in Pennsylvania and was brought by his parents to Pickaway County, where his father died when Jacob was 14 years of age. His whole life was devoted to agricultural pursuits. Jacob Ludwig died in 1881. He was one of the men of standing in his township, honest, upright and industrious, and enjoyed universal esteem. He left the homestead to his descendants after developing it into a fine, productive farm. His father built the first brick farm house in Pickaway County.
Isaac Ludwig was reared to man’s estate in Circleville township and attended the best schools afforded in his neighborhood. He was reared a farmer but when the Civil War broke out he proved that he could also be a soldier. With the Army of the Cumberland, as a member of Company F, 90th Reg., Ohio Vol. Inf., he served faithfully through 16 months and during this period he participated in the battle of Stone River and a number of lesser engagements, and was one of those who passed safely through the terrible battle of Chickamauga. Upon his return from the army he resumed farming.
On February 1, 1881, Mr. Ludwig was married to Charity M. Betz, who was born in Pickaway County, Ohio, August 28, 1863, and is a daughter of Daniel and Sarah (Root) Betz. The father of Mrs. Ludwig was born in Pennsylvania and her mother in Pickaway County, Ohio. Mr. Betz came to this county in boyhood and was reared on a pioneer farm. Of. the family of seven children born to Isaac Ludwig and wife, the survivors are: Cora E., M. Myrtle, John I. and T. Mildred, all living at home.
