Would anyone be familiar with mills in Cairo? Or point me in the right direction to find the info? My gggrandfather worked at the Haliday Mill in Cairo from about 1870 til just prior to his death in 1915. I can't find anything regarding any mills in Cairo. I am familiar with the Haliday Hotel which was owned by the same Haliday's that owned the mill-but that's all I have found. Thanks, Patti researching Gray's in Cairo, Ill and Troy, NY
