Georg Seckinger (son of Jurg Seckinger) and Christina Weßner (daughter of Johannes Weßner) married in Sulz am Neckar on 21 January 1708. Among their children was Johann Michael Seckinger, who was baptized on 8 June 1719. Johann Michael was confirmed in 1733. No record of his marriage was found in the Sulz am Neckar parish records.
