There is little if any dependence on another field's values for the values in a given name field. In some cultures there is a preponderant tendency for the oldest son to have the same name as the father's father. Yet both names do not usually appear in one record so as to be applied as individual identifiers. However, the chances that there will be agreement in unmatched comparisons depends greatly on what the value of the name is. A common name will have a higher coincidence value than a rare name, i.e., agreement in a common name is not as coincidental as in a rare name.
