Probable German birth name spelling: Nikolaus Körper
Nicolaus (Nicholas) [Kerber] Carper

Nicolaus arrived at Philadelphia with other Palatine passengers on 11 August, 1732 on the ship "Samuel" of London, [England]. Hugh Percy was the Master: from Rotterdam last from Cowes (English port on the Isle of Wight), Nicolaus’ name is spelled three different ways on three different ship’s lists: Nicholas Corber, Niklas Korper, Niklas Kerper. Nicholas Corber, age 22 is shown on the captain’s list (age error, 7 years younger than age shown at baptism, 11 mar 1702). Niklas Kerper is shown on the clerk of courts list when passengers took the oath of allegiance to the King of England & American Colonies. All passengers were examined before they were allowed to leave the ship.
Nicholaus Corper and Margaretha Masteller, of Skippach, married 3 December 1734. Note: Skippach is located west of Trappe Church, was then in Philadelphia Co., now Montgomery Co. Margaretha’s given name was not often preceded by Anna. Margaretha (Barbara) appears to be the correct name of Nicholaus’ spouse. Johann Casspar Stoever performed the marriage.
It shows that they were extensive land owners in Pennsylvania, and also made a living being a blacksmith at Coventry Forge that was located on French Creek, South Coventry Township.
In 1758, Nicholas Kerper was listed on the tax list then his name disappears from the Lancaster Co., Pennsylvania records. We can assume that he died there [sometime] after 1758.

He [Nicolaus] and Margaret lived in Cocalico Township, Lancaster County, PA by 1753. County records of him stop in 1758 (the only year he was taxed there). He was one of the first elders of the First Reformed Church of Coventry, East Coventry, Chester County, PA on 19 May 1743 when Rev. Jacob Lischy became pastor and started keeping records. He worked as a blacksmith. In 1740 they were 'of Plymouth in Philadelphia County.' 587
