Hugo, clerk CRI&P, residence Davenport I believe the city directories for Rock Island are on line. It may be on a PAID site. Maybe someone can direct you to the site. I know the Rock Island Historical Society has copies of the directories and I believe they may be on microfilm thru inter-library loan. The 1909 directory is the only one I have. Ruth J. Thompson
