I am researching Samuel Traster (b. 1818) who married Mary Markle (b. 1831) in Summit Co OH. It's believed that his parents were Martin Troester/Traster (b. 1764) and Catherine Shout (Schaut) (b. 1781) of Berks and Union Cos. PA. Martin Troester's father may have been John Martin Troester (b. 1743) of PA.
