7.3 Separate given names compounded. Now suppose a person carries the name of “Jean-Pierre.” This is a token of <Jean-Pierre>. What would be the consequences of viewing this as two given names, one a token of <Jean> and the other a token of <Pierre>? For record linkage the utility of doing so would be restricted particularly to the culture where people might mistake the name for one or the other or both. For example, if the individual carrying this name were to change residences into a different culture, that culture might not recognize the French compound name. The individual might analyze his given name into two pieces and choose one of them as a single acceptable given name. This situation is admittedly rare for the French nowadays. But it is very close to the difference in German countries between the baptismal name of <Johann Peter> and the name at marriage of <Peter>. The difficulty comes when we require a value specific comparison weight of "Jean-Pierre." There would be a low agreement weight for <Jean> and another low weight for <Pierre>. Would the sum of these two weights be anything like what the weight for <Jean-Pierre> ought to be? Possibly, but then it would have to have been by sheer chance. The agreement weight of <Johann> as a single name piece in German countries is very small, since 42% of the male children have it.
