DNA is another tool that can be used to prove the paper trail constituting the data used to constitute a genealogical family tree. It can also be used to find new cousins! Project administrators can help you decide on which DNA test to order and are available to help understand your DNA results. NOTE: Project administrators DO NOT do genealogical research for you.

Just after Brazil discovery, at the very primordial of Brazilian history, only very few individuals migrated alone - or with their original spouses - to populate the new world in South America. Those individuals' offspring were largely spread to the different regions looking for prosperity and richness. Beyond documental "classical" research, such as birth/death certificates, inventories, judicial records, press printings, etc. the Y-DNA and mt-DNA may be able to strongly connect the descendants of the historical figures and support/provide additional research data for the individuals performing their genealogical family trees.
