Biography
Johann Martin Schwartz was born at Dürrenzimmern, near Heilbronn in 1706, son of Heinrich and Dorothea Schwartz, and was called a Weingartner (vine dresser), when he married Anna Margaretha Pfoh of Schluchtern in 1728. Martin and Anna Margaretha settled at Schluchtern, where five children were born and baptized, three of whom died in infancy. In the summer of 1738 Martin, Anna Margaretha, and their two surviving children left Schluchtern with Hans Georg Sommer, his wife and child, and others from nearby villages and went to Rotterdam where they took passage on the ship "St. Andrew" and made the trans-Atlantic journey to Pennsylvania. They arrived in Philadelphia, October 27, 1738, and soon settled at Germantown, north of Philadelphia. Anna Margaretha and possibly their two children, died on the voyage or soon after arrival and by 1740, Martin was married to Margaretha Lohrmann, daughter of Peter Lohrmann of Schwaigern (a few kilometers from Schluchtern). Lohrmann and his family emigrated with a number of other families in 1737 and he wrote back to Schwaigern encouraging more people to emigrate and actually greeted the passengers of the "St. Andrew" when they arrived in 1738. Martin and Margaretha had at least two children born before they became affiliated with Saint Michael's Lutheran Church in Germantown, but in 1745 their son, Johann Martin, was baptized at Saint Michael's, another, son, Gottlieb, in 1747 and daughter, Anna Catherina, was born and baptized there in 1752. By the end of 1754 Martin and his family had moved to the Shenandoah Valley of Virginia, and on January 19/20, 1755, he purchased 120 acres on the west side of the North Fork of the Shenandoah River, in what is now northern Shenandoah County, but at that time was still part of Frederick County. By 1762 his sons were old enough to help with surveyors and several applied for survey warrants for themselves in the same area. Martin was deceased by December 1771, when his son Peter was granted a tract of 118 acres in December 1771 adjoining the line of "the late Martin Black."
