I checked my Chicagoland Atlas, which includes a detailed map of Lake County. I cannot find a cemetery by that name anywhere near Lake-Cook Road. I also checked TopoZone.com. I entered State: IL, County: Lake, and type: Cemeteries. I comes up with a long list of all the cemeteries in Lake Co, IL. None are named County Line Cemetery. Perhaps the name has been changed ? (In fact, there are no cemeteries with the name County near Lake-Cook Road in Cook County either). Wish I could have been more help, Cathy Koch Hoff [email protected]
