History of Lehigh County, Pennsylvania by Lehigh County Historical Society
Bauman Or Bowman Family John Dieter Bauman, the ancestor of this family in America, was a native of Germany and arrived at Philadelphia on October 2, 1727. He first settled in Marlboro township, Philadelphia county, where he secured 200 acres of land and owned and operated a grist-mill. In the year 1751 his name, with that of his wife, Eva Elizabeth, appears as sponsor at the baptism of a son of George Klein, in Lower Milford township.
About 1755, he removed beyond the Blue mountains, to Northampton county, to what is now Lower Towamensing township, Carbon county. Here he cleared a tract of land and lived until his death in 1762, leaving a widow and four children: Bernard, Henry, Mary, and Sabilla.
