I don't know about Maryland but I do know about the Palatine Germans expelled from the various German principalities for being variant religions. They made their way to English refugee camps in the 1720's and were eventually transported by the Crown to Ireland (most absorbed into the population) and to the New World, in exchange for their indentured labor making tar for the British Navy. They were not given any materials and had to build their own shelters, provide their own food, etc. while producing the tar. They also had to swear alleigence to the British Crown, which is why many of them refused to fight in the Revolution (many frin NY made their way to Ontario, in places like Norwich Township (see their online genealogy archives). There was a large contingent of Palatine Germans in Dutchess County, NY on the Beekman Patent (see Frank Dougherty's book, Settlers of the Beekman Patent, in your library). My Tanners settled there (James Tanner served as a Continental Army private in the Revolution, son of James Tanner; I haven't gone further back yet.). There is a list of their siblings in my Wikitree, or on ancestry.com.
