The naming custom of the Germans was to name the child after the sponsor of the child.
Note below the sponsor of John born Aug 3 1733 or Johannes Liebenstein.

I ask a researcher in Lancaster County to search Lutheran Church records of Muddy Creek Lutheran for a Bernard Livingston, Bernhardt Liebenstein or Lowenstein.

Some info that I got says.
