History of a Trease family in America. This link is to a nicely written story of a Protestant family with surname "Dreese" who left Germany in 1733 to escape religious persecution and settled initially in Pennsylvania. They sailed on the "Pink Lady", a British ship, and stopped at Plymouth en route. The family now seems to be mainly based in the Ohio area.The evolution of the spelling from Dreese to Trease (rather than to Treece, Treese, or Trees) is not researched in the history but seems very strange - it may be that 'Treases' lived in the same area and this unusual spelling was simply copied for their similarly sounding name. Like the UK Treases, they used the same set of christian names (Michael, Peter, Samuel, Jacob, Henry, James, John, Thomas, William, George). Interestingly, descendants from both families are Science PHDs who have majored in NMR and met at a conference in Switzerland in 2009.
