Howdy, I'm kind of related to the Coles around the area you speek. I have not come across Washington yet however. Its hard to understand the way you put Nebr City Nemaha Co. Because the actual City of Nebraska City (where I live now) is in Otoe County, Nebraska. Nemaha is next to us. I have collected alot of information on the Coles, I may be able to help you. Send me a e-mail and we can maybe talk this out. I want to know exactly what you have.
