The next few sections of this chapter discuss the results of an analysis of a certain corpus of data. We detail record linkage algorithms involved in deriving a lineage-linked pedigree from the individuals in a set of family groups. The documents we begin with — the corpus — are the family group sheets of the 1942–1970 archives collection — the family group record archives (FGRA). Universal data entry (UDE) computerized these data and fractionated the families into individuals for indexing by the International Genealogical Index (IGI). The first step preserved the family group sheet model translating the data into GEDCOM format. The second step, however, transformed the data into the IGI individual and family (marriage) model. The idea of this chapter is to explicate algorithms required for use on this particular corpus using principles of analysis that are general enough to apply as well to record linkage in any other collection.
