Over time, the world population has developed a desire to research their ancestoral linage. Many resources have been identified to aid an individual in genealogical research. In the United States, one of the greatest resources for researching genealogy is census records. Census records allow a genealogical researcher to track individuals over time, broadening the scope of information one can acquire about an individual. Dr. Halbert Dunn first presented the concept of record linkage in 1946 to describe the process, which joins two separate pieces of information for a particular individual or family [Dunn 1946]. Later, Fellegi and Sunter  built upon Dunn’s foundations by establishing a probabilistic mathematical approach to record linkage. Probabilistic methods for record linkage have been developed to mimic the decision process of genealogists and researchers. An automated probabilistic approach allows the researcher to conduct many different types of searches within seconds. Following an automated search a list of record matches (links) as well as potential matches (links) with information necessary to further explore each potential record pair can be made. This enables a researcher to compile large numbers of records in a fraction of the time it would take to process manually
