Katie and Franz Largmann

Possibly wedding photo taken in Germany at either Saargemünd or Zweibrücken probably of Katherine Schwegel and Franz Largmann.

There was nothing written on the back, however they resemble two labled photos of a later date that identify the man as Franz Largmann and the woman as 'Katie' which could be a Katherine or Katherina or Catherine or Karolina or Carolina Schwegel. It would appear that they were married in Germany, are related to the Schwegel family that settled in Schrollbach, Deitzweiler and general Pfalz area of Germany. The rest of the immediate family moved to Millville, New Jersey and Philadelphia, Pennsylvania. Do you recognize these two?
People in photo include: Katherina or Katie Schwegel Largmann and Franz Rooss Largmann
