CHARLES D. FOLKERTH.     A native son of Darke county, Charles D. Folkerth was born on a farm in Greenville township, Nov. 20, 1870, and is a son of L. D. and Rachael (Cox) Folkerth.  His father the present treasurer of Greenville township and a retired farmer, is living on Switzer street, in the city of Greenville.  L. D. Folkerth was born Apr. 2, 1842, in Green township and is a son of Jesse and Anna (Curtis) Folkerth, the former of whom came from Montgomery county in 1808 and located in Greenville township, where he entered land from the government.  Jesse Folkerth was one of the early stockmen of Darke county, carried on extensive operations and became widely and favorably known in business and agricultural circles.  He and his wife were the parents of five children, as follows:  William, Maria, who married Mr. Swank; L. D.; George, who is deceased, and Christ.  L. D. Folkerth was given ordinary educational advantages in the district schools, principally in Van Buren township, and at the age of fifteen years entered upon a career of his own by working by the month.  For forty years before his retirement he resided on the Studebaker farm, and then located in Greenville, where he purchased the property on Switzer street, where he now resides.  He was married in 1862 to Miss Rachael Cox, and they became the parents of four sons:  William, who is married and has three children: Jesse, who is the father of six children; Thomas, who has one child; and Charles D.  Mr. Folkerth's second marriage was to Miss Fannie Purdy, and they became the parents of three children: George, who has one child; Ora, who has two children, and Harry, who is deceased.  Mr. Folkerth is a veteran of the Civil war, having fought gallantly in the Union army as a member of Company G, Forty-fourth regiment, Ohio volunteer infantry, and has proved himself just as faithful and courageous in fighting the battles of peace.  A Democrat in his political views, he has been prominent in the ranks of his party, whose candidate he became for the office of township treasurer, being elected thereto at the ensuing election by a satisfactory majority.  In this office he has rendered his fellow citizens signal service and is proving conscientious and faithful in the discharge of his duty.  With his family, Mr. Folkerth attends the Christian church.
     At the age of seven years, Charles D. Folkerth began to receive his educational instruction in the Studebaker school, which was located south of Greenville in Greenville township.  This was subsequently supplemented by attendance at an insituation at Daleville, Va., where he took a business course, and upon his return to Ohio worked on a farm up to the time of his marriage.  He then rented a property from Joshua Delaplane for some time, subsequently entering the stock business, and then went to Castine, Ohio, where he embarked in dealing in agricultural implements.  He continued thus in connection with buying and selling stock, and by good judgment, foresight and well-directed management was able to make an unqualified success of each venture.  Later, however, he answered the call of the soil, purchasing his present farm of one hundred acres, located on the Fort Jefferson road, one-half mile south of Fort Jefferson, where he has continued to follow agricultural pursuits to the present time.  Mr. Folkerth has worthily won the proud American title of “self-made man,” for all that he possesses he owes to his own efforts and energy.  In addition, he has not only won a comfortable competence, but also shares in the high regard of his fellow-citizens, and justly merits the esteem which is so generously accorded him.  In political matters he is a Democrat, and his religious connection is with the Methodist Episcopal church, of which his wife and children are also members.
     Mr. Folkerth was married (first) to Miss Laura Delaplane, who is deceased, and to this union there were born four children: Thomas D., Robert J., James O. and Ralph R., the last-named being deceased; Mrs. Folkerth died May 10, 1902, and was buried in Fort Jefferson cemetery.  On Nov. 28, 1907, Mr. Folkerth was married (second) to Mrs. Luella (Royer) McCabe, the widow of Mack McCabe, who had three children by her first union: Fay, Sylvia and an infant deceased.  Mr. Folkerth has a pleasant home, surrounded by handsome and substantial buildings.  Until destroyed by a windstorm five years ago, there was located on this property one of the largest coffee-nut trees in this country, to see which people came from all over the United States.  A picture of this tree is now hung in the Smithsonian Institute, New York.

Folkerth, now living a retired life at Greenville, where his pleasant home is located on Switzer street.  His life has been a busy and useful one and furnishes an example of honorable dealing, steadfast purpose, fidelity to principle and invincible moral courage that is well worthy of emulation.  He has rendered his fellow-citizens signal service in offices of responsibility and trust, and at this time is acting efficiently in the capacity of treasurer of Greenville township.  Mr. Folkerth was born April 2, 1842, in this township and is a son of Jesse and Anna (Curtis) Folkerth.
