Dear Maria, I am excerpting a piece from "The History of Saginaw County" found at the Hoyt Library in Saginaw...foolishly, I did not make proper notes for author and date of publication. "JACKSON-CHURCH-WILCOX COMPANY, Division of General Motors. In the new, modern plant of the Jackson-Church-Wilcox Company, division of General Motors, Saginaw has a vaulable acquistion to its manufactures...The original company was incorporated on April 21, 1906, by John L. Jackson, Edgar D. Church and Melvin L. Wilcox...The machine shop was first located in a two-story building at Hamilton and Madison Streets, formerly occupied by the Saginaw Street Railway, but which was then a part of the Jackson & Church plant...Not long after the shop was running smoothly, making essential parts for some of the leading automobiles, the attention of the company was directed to a radical improvement in steering gears, a patented device by which the ideal condition of driving was obtained. The company begin making the new gears on a small scale, and soon proved the practical utility of the device. Afterward, when manufacture was largely increased, the company purchased the patent rights and gave to the improved gear the trade name of "Jacox", derived from the names of the incorporators...In 1909,...a site for new shops was purchased at Hamilton, Monroe and Niagara Streets. A new plant of the most modern construction was here erected and equipped with new automatic machinery, the most part for the manufacture of "Jacox" gears. Their largest customer was the Buick Motor Company, of Flint, whose requirements were constantly increasing and assuming mammoth proportions. In order to control the entire output of the new plant, and expand the business to meet its future needs, the Buick Company bought the entire property of the Jackson-Church-Wilcox Company, including its patents and good will. The transfer was duly made, and on January 20, 1910, was held the first meeting of directors of the controlling interests -- the General Motors Company..." My great-grandfather, James McGregor, Jr., sold his family's boilermaking business to E. D. Church in 1899, and the firm was an intergal part of the original "Jaycox" corporation.
