I have copies of original extracts from the Evangelical Church records of Beutelsbach (Dekanat Schorndorf, Germany) of a Geywitz family, namely Jakob Friedrich G. marriage 23 Feb 1841 to Christiane Rau, and their children, and ancestry back to Frantz Geywitz and Barbara Weidlin in Urspring (Dekanat Ulm, Germany) and their son Hanns Geywitz, born and baptized on 29 May 1629.
All male members of this family were wine-growers, except for Frantz, who was a farmer.
Yet I could not find connections with the information in the messages on this board. On one of the pages of the copies that I have was one person listed "in Amerika" (Johannes Geywitz, b. 13 Nov 1812) and one "in der Fremde" [= abroad], (Gottlieb Geywitz, b. 29 Oct 1816).
