Margaretha married Martin Schwartz, from Schluchtern (a few kilometers from Schwaigern), who arrived in Philadelphia in 1738 and lost his wife, either on the journey or soon after they arrived. The were married by 1740 and lived at Germantown, north of Philadelphia, where three children were baptized at Saint Michael's Lutheran Church. In 1754 the Schwartz family left Pennsylvania and moved south to the Shenandoah Valley of Virginia, where they took up land near the North Fork of the Shenandoah River, in what is now Shenandoah County, Virginia.
