Johann Stephan Klaus, son of Johann Caspar & Anna Barbara Claus, was baptized in the village of Düdelsheim on 29 December 1717. He married Susanna, but she evidently died before he left for Russia. Johann Stephan is listed as a widower on his request to leave Düdelsheim.
He arrived as a widower in Balzer on 1 July 1767 and is listed there on the 1767 Census in Household No. 4. Four of his children are also listed there: Johannes (baptized 8 September 1748), Susanna Catharina (baptized 29 August 1751), Johann Peter (baptized 1 March 1754), and Johann Adam (baptized 1 August 1756).
Decker incorrectly identifies this Klaus family (p.82).
