Mareen Duvall was a Jacobite

Mareen Duvall the Emigrant was a leader in the Jacobite Party in Maryland.  What this essentially meant was that he was a believer in the "divine right of kings", and sided with Scotland in supporting James Stuart (King James II), the son of King Charles II, to be King of England.  In a letter written by Colonial Nicholas Greenbury, he refers to a meeting of Jacobites held at the home of Mareen Duvall. See "Side-ligths on Maryland History, With Sketches of Early Maryland Families, by Hester Dorsey Richardson, v. 2, 1913.  It would be interesting to know if Mareen Duvall had been around 100 years later if he would have supported the Revolutionery War, as did his descendants, as his Jacobite position might have interfered with his support of the War.
