Hey C., here is what the record says:
Transkription: [1730] ''Johann Bernhard Christoph Kretzler, Hufschmied, Jacob Kretzlers, gewesenen Bürgers zu Ordruf in Thüringen ehel. Sohn; u. Frau Eva Ritterin, weyl. H. Christoph Ritters, GerichtsVerwandten allhier, hinterlaßene Wittib, wurden nach gehöriger proclamation copulirt den 13. Junii.''
Translation: "Johann Bernhard Christoph Kretzler, Farrier, legitimate son of Jacob Kretzler, former citizen in Ohrdruf in Thuringia; and Mrs. Eva Ritter, widow of the late Mr. Christoph Ritter, alderman here; got married on June 13th 1730 after proper proclamation."
So it seems the husband was dead already. It therefore depends on how much you trust the source for the second marriage. If he indeed would have married in Eppingen, the marriage would have to be in the same book, which it isn't. More research is needed, but it seems the second marriage is wrong.
