Hello,
A T Boney and Co. was located in the village of Cairo, Randolph County in Missouri. 2010 census states a population of 292. I have a sign just like yours Malcolm, and the seller told me the location was in Missouri. I just finished a Google search and can confirm this. A T 's first name is Arthur. He married a woman, and she passed away, and then married her sister, who helped raise his 2 children, a boy and a girl. I wonder what the Internet has to say about me, kinda scary... Hope this helps. Tim
