This historic house, located at 924 S. 6th Street, is included in Dr. F. S. Barringer's "Historic Homes of Springfield," published in 1966. I believe it is out of print. The notation reads: "This house, retaining so much of the grandeur of early Springfield, was built in 1867. The builder was Wm. A. Turney, who was born in Galena in 1832, married Maria Warren, and came to Springfield as a young man. Turney was an attorney and became clerk of the Supreme Court. The Springfield Director of 1869 records -- "Turney, William A., Clerk of the Supreme Court, 6th between Cass & Clay Streets." "In his early years as an attorney, Turney spent sometime in New Orleans obtaining right of way for the Illinois Central RR. It was shortly after this that he built this house, and the effect of this trip to the deep south is immediately obvious in the architecture of his home. The beautiful iron grill work of the balconies was brought heere from the south, and the design and trim of the windows with their inside shutters suggest the French influence of New Orleans. "The house was one of the finest of Springfield at that time and became a center of the social life of the community. Mr. Turney died in 1875 and his wife in 1899. The home was left to two daughters, Annie, who married Thomas Baird, and Maude, who married James A. Kimber. The two daughters and their families then occupied the house jointly, and Mrs. Kimber in later years told of the many gay parties and soirees of those early days. Mrs. Baird died here in 1931 and Mrs. Kimber lived here til her death in 1945. William Kimber, son of Mrs. James Kimber, still resides in Springfield. "In 1921, the large central stairway was removed and the interior altered so that the home could be converted into four apartments. In 1945 the house was sold to Wm. Frasco of Riverton. Mrs. Grace Potter, widow of James Arthur Baird, son of Annie Baird, still lives in the grand old mansion. "The house interior still retains much of its original grandeur despite the modification of the 16 rooms. In the front room of Mrs Potter's apartment are large oil paintings of Wm. and Maria Turney, both handsome and aristocratic personages. The ceilings of the rooms are quite high and the wood trim ornate. The furniture which is victorian or mid-19th century, includes marble top tables, handsome mirrors, and a beautiful old ship's desk. "The entire house, both exterior and interior, still breathes the life of one hundred years ago. We pray the house will not be torn down and may be left to live on, a memorial to a chivalrous past." The book includes a 1966 photo, as well as an earlier one "from the collection of the late Mrs. James A. Kimber." It does not mention a John Turney, and lists only the two daughters. Some of the dates don't match those in your query. Hope this answers some of your questions. D. M. Ross
