Applications to a Lineage Society or Duel Citizenship.
Many people find enjoyment finding a connection to a country or organizing. These people, if they qualify seek to obtain duel citizenship or apply for membership in an organization such as the Daughters of the American Revolution (DAR) or Mayflower Descendants. Dual citizenship and membership applications all have different requirements. The one thing they usually have in common is proof of your relationship to an individual from the country or a member from that organization.
A genealogist can help find the relationship evidence you need for such applications or may be able to apply on your behalf. Many organizations have genealogists who review pending applications. Hiring a genealogist who is familiar with a specific application process can improve your chances of an application being accepted.
