Peter Trexler emigrated to America some time prior to 1720 and settled in Oley township, Berks County, where his name appears on a petition as early as Sept. 5, 1720. He afterward removed to Upper Macungie Township, where he is said to have been the first white settler. On Nov. 18, 1729, he purchased from Caspar Wistar 138 acres of land west of where Breinigsville is now located and the date of his deed precedes any yet found in the vicinity. On Nov. 1, 1742, he secured 100 acres of warrant, adjoining his other land on the west. He was naturalized in 1730. Peter Trexler died in 1758 and was buried on his land. He was a member of the Lutheran congregation at Ziegel Church. His will, dated Dec. 17, 1744, was probated at Philadelphia, Oct. 21, 1758. The witnesses were Gittie Grim and George Schambach and in it he proved for his widow, Catharine, and bequeathed his eldest son Peter, received his land and was appointed executor. He had six children: Jeremiah, Peter, John, Anna Catharine, married Nov. 9, 1730, John George Schulmacher and Margaret.
