The analysis of g-isonymy data.
g-Isonymy is defined to be generalized isonymy, and is taken to be two (or more) individuals who have the same surname (clan name) and who are related through marriage, although they are not necessarily married to one another. A general method for analysing g-isonymic data is proposed. It is shown how the random and non-random components of the frequency of g-isonymy can be obtained as well as the subcomponents due to preference for or against close consanguineous marriages and/or for or against remote consanguineous marriages. The proposed analysis, is applied to a subset of data on the Bhatias, a community which practises strict clan exogamy.
