I'm a great-great granddaughter of Henry Blakely Hutchinson and Rebecca Whiting Wilkes. (Octavius Nelson Hutchinson is my great grandfather.) I haven't been able to find confirmation of Henry Blakely's parents. What I have found about Thomas Leach (son of Henry and Susannah Leach Hutchinson) says that he died without children. If anyone can clear up this mystery, I'd appreciate it!
Here's info about the Grand Crossing Tack Company in case you haven't found anything...I know your question was a long time ago! "In 1883, E.W. and O. N. Hutchinson founded the Grand Crossing Tack Company to make carpet tacks. Their small plant was located at 79th and South Chicago Avenue. As the business prospered and expanded they decide to produce their own steel rather than purchase it. They built a mill on the east bank of the Calumet River in 1902. In 1916, Interstate Iron and Steel of East Chicago bought the Grand Crossing Tack Company. In 1930, when Republic Steel was formed Interstate became part of the merger that formed the new company."
