I am searching for the Marriage records of Alexander C Jack and Almedia A Duke. I believe they would have married just prior to 1880. I find them in the 1880 Izard county census with a 6 month old daughter. I believe they were in Sharp County before they were in Izard County. Also any other Jack in Sharp county, that would have been Alexander's brothers or sisters. I would appreciate any help. Thanks, Bev Jacks
