Another prominent researcher, Nancy J Emmert suggests in breaking a brick wall is to look at patterns of migrations that ancestors may have taken, research the other family members to find clues on the ancestor who is the brick wall, and study the census while using the “ten up and ten down” rule. An example of the “ten up and ten down” rule is to look at the ten families above your ancestor in the census and then check the information for the ten families below the ancestor. Many times a researcher may find the original ancestor’s family members living down the road or with neighbors (Emmert).
