ISAAC DECKER, one of the old pioneers of Wells County, who is now deceased, was born in Berks County, Pennsylvania, in 1820, a son of Christian and Elizabeth (Albert) Decker, who were natives of the same State. He spent the early part of his life on a farm in his native county, and when a young man went to Fairfield County, Ohio, where he was married to a Miss Langle, and to this union was born one daughter--Lucinda. After his marriage he immigrated to Jay County, Indiana, where he resided for a time, when on account of the ill health of his wife he returned to Fairfield County, where his wife died. He was again married in Montgomery County, Ohio, to Miss Elizabeth Houser, a daughter of Henry Houser. After his second marriage he returned to Jay County, Indiana, but his health failing he returned to Montgomery County, Ohio, where he made his home until 1853. He again returned to Indiana and settled on a farm in Rock Creek Township, Wells County, which his father had previously bought, and after residing there a year and a half he removed to Huntington County, and settled on a heavily-timbered farm of 160 acres which he had bought some time before. He cleared this farm and made improvements, residing on it eighteen months, when he returned to his father’s farm in Wells County, which contained 160 acres. When he settled on this farm only nine acres had been cleared. He cleared and improved the remainder of the laud, and here he followed farming the rest of his life. He died in 1868, at the age of forty-eight years, his widow surviving until 1872, her death occurring at the age of forty-seven years. They were the parents of ten children, five of whom still survive—Edward, Christena, Mary J., Maria R. and Isaac W. In his political views Mr. Decker was a Democrat. He was an active and public spirited citizen, and was always interested in any enterprise which had for its object the advancement of his township or county. Edward Decker, the eldest son of Isaac Decker, is one of the enterprising agriculturists of Rock Creek Township, and a highly respected citizen. He is a native of Ohio, born in Montgomery County, July 19, 1846. He was seven years old when his parents came to Wells County, and here he was reared on the home farm, receiving his education in the common schools. He resided with his parents until their death, when he succeeded them in the old homestead, where he still follows agricultural pursuits. He was married in 1869, to Miss Rebecca L., daughter of John Houtz, of Rock Creek Township. They are the parents of seven children—Lydia E., Davilla N., George E., Charles W., John F., Rufus L. and Otto R. Both Mr. and Mrs. Decker are members of the Reformed church. In politics Mr. Decker casts his suffrage with the Democratic party.
