Biographical Sketch (1985):1513, p. 1. "Our shared heritage is in the name Lerch, generally spelled in Germany as Lörch. Lörch evolved in the United States as Loerch, with the e after the o taking the place of the umlaut. Because the pronunciation of Lerch is close to the German Lorch, the o has all but disappeared from the name in the United States, leading to the widespread spelling of Lerch. Lörch in German means lark (a bird). Prior to the Revolutionary War when the Berks County Courthouse records were recorded in English, the English translation "Lark" is generally used for Lerch, such as Caspar Lerch’s (Lark’s) will in 1766."

Biographical Sketch (1985):1513, p. 5. "A brief account of the trip to American was left to the ancestors of Nicholas Lerch via his widow, Margaretha. Margaretha’s traditional history states that in in the spring or early summer of 1738, the family of Caspar Lerch left its home and wended its way to Hanau on the Main River. They floated down the Main to its confluence with the Rhine River and thence to the port of Rotterdam. At Rotterdam they boarded the ocean-going vessel Queen Elizabeth and sailed for Deal, a port in England. At Deal they took on provisions and additional passengers including Andreas Lerch and family who had previously left Germany and had taken the offer of land from Queen Anne preparatory to sailing to American. The ship landed at Philadelphia, 16 September 1738, having at least 300 passengers on board."
