Mareen Duvall "The Immigrant" was a Huguenot that was given a Maryland land grant in the 1600s by the Calverts. Since then, many of his descendants have been notable people.
The genealogy around the man, particularly the claims of Mareen's ancestry, is often controversial among his descendants. The goal of this project is to provide Geni with the most accurate data we can possibly come up with. When controversy arises, uninvolved parties should be called upon to settle disputes (That is, Curators without direct lineage from Mareen.)
Any and all help is appreciated and encouraged. All discussion of the Duvall family takes place in this thread.

- Harry S. Truman, President of the United States is Mareen's 6th Great Grandson
- Barack Obama, President of the United States is Mareen's 9th Great Grandson
- Dick Cheney, Vice President of the United States is Mareen's 8th Great Grandson
