HI Jean There is a write-up in "A History of Fulton County Illinois in Spoon River Country 1818-1968" about this Geo. Duncan as follows: George Duncan was born in Edinburgh, Scotland in 1787. He was educated to be a physician in Glasgow, but gave up his profession, coming to America in 1816. He first located in Pennsylvania and while there helped to survey for the Erie canal. In 1835, he went to Shawneetown, Ill, but soon moved to the beautiful and picturesque spot on Spoon River, now known as Duncan Mills. At this spot there were rapids in the river suggesting to him the erection of a dam and flour mill. Thus came into being the famious Duncan Mills, completed in all probablility in 1836. The mill became famous for miles around, as this was a sawmill with burrs for grinding wheat into flour. The grist mill was built soon afterwards. One of the remarkable things was that the mill ran through winter's ice and summer's drought and only a great flood could make it be silent. Mr. Duncan had able assistants in his sons, John and Thomas, and his bachelor brother, Henry. There is more written on him, but I hope that this tidbit will help you to identify is this is your George. I would be happy to send you copies of the write-up if this turns out to be your line. Hope this helps...........Bev
