Elk Garden, also known as Burnam House, was owned by Thompson Burnam, Sr. from 1825-1849. There is an excellent account of a piece of Madison County history on the "HISTORY OF THE PETER TAYLOR FAMILY (1746-1812)" Website that mentions Thompson.

"(Pg. 24) Tabitha Taylor's Wedding: I have a statement in my papers as to the wedding of Samuel Phelps (1788-1852) and my grandmother, Tabitha Taylor (1800-1869). The marriage occurred at the home of her mother, Mrs. Peter Taylor, on January 3, 1822, at 4:00 P.M., then the fashionable hour for dining. Mr. Thompson Burnam, Sr. told my mother, shortly after her marriage, that he rode down with the groom and his friends, Mrs. Burnam, Mrs. Lucinda Field of the Field Family of Culpeper County, Virginia, and Mrs. Taylor's family (William Burnam's Family were friends in Culpeper). The day was clear, but it turned suddenly cold, the thermometer going below zero in a few hours (So, Mr. Burnam said he and Mrs. Burnam for this reason, did not attend the wedding). He said that Samuel Phelps rode the handsomest saddle horse he had ever seen (He was known through life for the handsome horses he rode). He spoke of the great open fires, many candles, and the superb dinner, which was served for the wedding of the youngest daughter of the family."
The Farmers Bank Building is on the National Register of Historic Places in Kentucky. It has always been a bank and was added for it's classical revival style of architecture for the historical significance between 1900-1924. It's a tiny building, but you can't miss it, seeing as to how there aren't that many buildings left still standing in Kirksville town anyway.
