I'm going to be visiting Highland Co. for only about a day to do research on dead relatives. I'll be looking for infomation about John Henry Sellers and Grover Carey Sellers and their families. John Henry arrived at Greenfield from Delaware Co. in about 1845. He was a farmer, pump-maker, and tannery owner. I believe his son, Grover, founded the Sellers Monument Company at the Greenfield cemetery. What sources should I be sure to visit in my genealogical research? Thanks, John Sellers Hoffman Estates, IL Researching: Downing, Fullerton, Harbour, Mottie, Patton, Prosser, Purdue, Reynolds, Sellers, Wells, Wood.
