Karan, It is difficult to determine who your great grandmother is from the information you have given me. The William Book has many "Elizas". Some died young, some are listed as married to others and some just have birth/death dates. If you could provide an era, i.e. time frame, area/state, and/or children, it would assist me in trying to locate your g-grandmother. I will not be able to respond for a couple of weeks. But I will try to get back to you as soon as I can. Julia
