Carefully study the material that you have collected. It is time to select a goal and begin your search in earnest.
A goal is achieved by asking and answering questions. As you look at your group sheets and pedigree chart pick the relative closest in time to you that has missing information. It may be a parent, a grandparent, a great-grandparent.
If possible, call relatives. Someone might have the information that you are seeking.
If not, it is time for the detective work to begin.
Census records are a great place to start. The Federal Census is taken every 10 years. Begin to create a timeline for the ancestor that you have chosen. When was he/she born? When did he/she die? What census records exist for that time span?
