SAMUEL HINKLEY (Deceased)
The Hinkley family were early settlers of Johnson county, where they have-taken a prominent part in affairs. Samuel Hinkley was born at Brookfield, Madison county, New York, December 20, 1818, son of Luther and Eunice (Burdick) Hinkley. He lived in his native place until 1855, when he and his brother H. L. emigrated to Johnson county, Iowa, and settled on farms nearly adjoining each other, in Fremont township. The brothers helped each other during busy seasons and were very close to each other in their friendship and sympathy. On this farm Samuel Hinkley spent the remainder of his life. He was married on April 22, 1857, to Miss Adeline A. Perkins, also a native of New York. She was born near Skaneateles, and when she was about one year old her parents moved to Pennsylvania and later to Erie county, New York. In May, 1853, the Perkins family removed to Johnson county, Iowa. The parents, Elihu S. and Sarah (Dubois) Perkins, had six children, namely: Mrs. Hinkley, Sarah L., John Thomas, William Gordon, Caroline M., and Lucretia Ann. The only ones of this family now surviving are Mrs. Hinkley and her sister Caroline, Mrs. Palmer, of Corry, Pennsylvania.
Mr. and Mrs. Hinkley had two children, Wiot R., a sketch of whom appears in this work, and Julia Z., Mrs. Jessie Holdeman. They also had an adopted daughter, Jessie, Mrs. Charles Patten, of Fremont township. Mr. Hinkley passed away January 30, 1908, sadly mourned by the entire community where so many years of his life had been spent. He had made his good influence felt in local affairs and had made a large number of friends. Mrs. Hinkley now makes her home with her daughter, Mrs. Holdeman, and Mrs. Patten. On April 22, 1907, less than a year before the death of Mr. Hinkley, he and his wife celebrated their golden wedding, a memorable affair, where they were surrounded by their children and grandchildren, friends and neighbors. Mr. Hinkley was always a republican in politics and served some time as school director.
