- to identify the unique Y-DNA profile of the different Guittard lines in France, America, Spain, and everywhere else and find which lines are related,

- to help trace each different Guittard line in France, Spain and elsewhere back as early as possible -- wherever the trail may lead -- and to trace each immigrant Guittard line back through its immigrant ancestor to the old country,

- to enable Guittard descendants to verify and confirm the accuracy of their tracing back to an alleged Guittard ancestor,

- to find Guittard cousins in France, America, Spain and elsewhere to exchange information, and

- to help focus our traditional, records-based Guittard research on the names, places and times most likely to be productive. (
